How do we get the gas out afterwards? The fluorine gas remains trapped forever. As to your second point, time doesn't pass in a storage seal and the reaction is kinda slow, unsealing it wouldn't get you much gas at all.
The last time she let Hazou do it and Noburi whooped his ass for it. Now, not only does Hazou not have a plausible excuse, but Ami is involved. Hazou can't threaten to sunder all of reality if he's been thrown into a caldera.
Although, the Gouketsu do own the rights to the Icha Icha franchise. Might be room for some thinly clad omakes there. Something along the lines of being forced to marry a titanic twenty-ton spider while an actual ethereal made of shadows and magic tries to figure out how confess her love.

Doesn't work that way, we tried boosting youthanizers by dumping implosion seals full of air into them. It didn't release the stored air when destroyed via fireball.
That's with a seal designed to release air when destroyed in an implosion. UGLSPs aren't even designed to release their contents when destroyed.
Solidified fluorine gas would be useless? We want it to react with our targets. The Air Domes don't really do what you're suggesting anyway. We shouldn't waste time researching a special seal for this idea. It's not a good enough weapon compared to regular explosive seals.

As the first tendril touched Jiraiya, he took a deep breath in and unsealed a strange, double-sided seal. Crimson clouds burst forth as he destroyed it, causing the wood to wither away instantaneously.
It was Sasori's turn to be shocked. "Why are you carrying concentrated herbicide into battle?"

I don't recall this. I recall stacked implosion seals which I called in advance would result in a sealing failure. I also recall that the purifier seals have a known failure mode of dumping their contents upon destruction just like storage seals because they are basically just modified storage seals.

Tunneler's Friend/SIN-1 with youthenizer. Fire needs air, so a paired seal releasing air may magnify the fireball. If SIN-1 works, try SIN-2 and SIN-3.
I'm not 100% sure what you're looking to try with this so I'm taking my best guess. You strapped a youthenizer seal and an implosion seal to the same kunai and threw it. You ran the experiment multiple times. Sometimes the youthenizer went off first and destroyed the implosion seal before it fired. Sometimes the implosion seal went off first and destroyed the youthenizer before it fired.
Actually, this brings to mind another option. Reactive armor is limited in where it can be placed without blowing off the user's limbs, but what if the same trigger were applied to a storage seal? Ideally, it would automatically dump its contents right back in the face of the one throwing the projectile, but even just sucking it up would be very effective armor against weapons users.
Hey, dead bodies can be safely stored in seals, so what about amputated limbs? Might be effective against taijutsu specialists as well if it's designed to rip off and grind up anything within a certain range of it's activation. Heck, since the entry shear stresses can be used to grind up a human body and a ground body is just a corpse anyone who punches somebody wearing one could end up being vomited right back out as a hypersonic bloody sludge complete with skeleton-derived abrasives.
What is the old rocket engineer's advice about working with fluorine? Something about the best protective equipment being a good pair of running shoes?
"If you're doing this for yourself, then that means you can stop. Please stop. Mari is precious to us. To me, to Noburi, to Akane, to Kagome… She's like a mother, or a sister, or an aunt, or something else we don't have words for. She is to us what she was to Kei before Kei cut her off. If you hurt her, you'll hurt all of us, deeply. If you kill her, you'll leave a hole in our hearts that won't heal. I'm not asking you for Kei's sake. I'm not asking you for Mari's sake. I'm asking you for ours."
I'm not sure what it means, because it's 1am here and I'm dead on my feet and I've just had this realization about the parallels, but it means something.
Ami also knows that we understand their love for Kei a bit more than other people might --at least in terms of how dear Kei is to Ami. And that sense of being understood must be validating, and the context that validation has arrived in must hurt... All the more because of how much Hazou has shown to understand Ami, and how much he's growing to understand them, ever-more.
Poor Ami. This emotional-vulnerability-thing, this being-understood-thing isn't something she signed up for.

"We only met because you miscalculated and a genin deciding to face off with a jounin on their prepared home territory was the only way to save Kei's life. Also, still haven't forgotten about your little prank almost getting me murdered by an armored alien drill sergeant from another dimension."
The result would probably be a kiss on the cheek from the ^_^ dowel, but it would be satisfying to say.
"Chakra monster," Kagome said, "Half plant, half animal, likes to crawl into an orifice, travel to your brain and then slowly eat it until it can totally control your body. Can use any chakra technique you know. Lupchanz."
Hazō shuddered. "That sounds horrible," he said. "I'm not a lupchanz though. I'm me."
"Yeah, that's what a lupchanz would say," Kagome said.
"You know what this means, right?" Kagome said. "Those stinking ninja stinkers in Leaf are going to burn that place to the ground. Then they'll fan out through the country looking to see if they missed anyone, and stick them in boxes to use as chakra batteries for tired ninja. Maybe they'll just put trained lupchanzen in our ears so that we do whatever they tell us. Then the other Great Village stinkers are going to decide they don't like Leaf having a large force of expendable lupchanz ninja, so they're going to unite and attack and it's going to be World War Three all over again, except this time it'll be World War Four."
He's really fixated on lupchanz right now, but I'm willing to bet that he will never mention them again, or maybe even that he made them up, but now doubts whether he actually made them up or whether the memories were implanted in his head.
My name is Ishihara Akane. When I was at the Academy at Hidden Leaf, there was a senior who talked exactly the way you do, about hard work and never giving up and the importance of the burning passion of youth—he even used those exact words.
"Higher! You can do it!" Hazō shouted, leaping into another tuck-jump. "Feel the springtime of your youth burning within you! It is a fire that lifts you up!"
What is the old rocket engineer's advice about working with fluorine? Something about the best protective equipment being a good pair of running shoes?
It is, of course, extremely toxic, but that's the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water—with which it reacts explosively. It can be kept in some of the ordinary structural metals—steel, copper, aluminum, etc.—because of the formation of a thin film of insoluble metal fluoride that protects the bulk of the metal, just as the invisible coat of oxide on aluminum keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.
I don't think this is right. Just from poking around on the internet a bit, it looks like it needs to be specifically nickel or nickel alloy to get the surface passivation effect, ordinary iron won't cut it. We probably don't have access to pure nickel. So I'd say a UGLSP is the way to go. Conditioned on us being able to retrieve the gas by destroying the seal.
Alright so since we're discussing fluorine ideas, if we can heat things up under pressure where there's oxygen and fluorine, and then we cool it quickly, we can get a compound called dioxygen difluoride, also named FOOF laughingly because it burns so much.
It's so ridiculously reactive it's caused a number of accidents through autoignition in labs at temperatures below 100K. Negative 300°F. Let that sink in. The sink has waited long enough to be let in.
If we can do that with nice seal-based protection near the caldera we keep talking about, and mix some fumes from the volcano in it as well for added hydrogen sulfide, the result is... well a very very nice explosion, but also we're left with reasonable quantities of hydrogen fluoride. It's a gas that dissolves human tissues.
Not that any of it can or should make it into a plan - it's impractical and far-fetched while there is ninjutsu that does exactly that.

The Comprehensive Guide to Putting Down the Horror We Called Up
The way I see it, there are various "modules" we can optimize separately, some of them optional. Namely:
Looping Asuma in (optional).
Keeping Hazou ignorant (optional).
The kill method.
The cover-up.
The aftermath.
I'll go in order.
Looping Asuma in is not as obviously correct as I've seen discussed on Discord. Critically, he's a very known quantity to Ami, and us telling him everything she'd threatened absolutely can't be something she didn't account for. She has some way to completely shut down that avenue of attack. Now, we might be able to convince Asuma to go against her anyway, despite the political costs, despite the ruinous contingencies, despite whatever other arguments she might make. After all, her moves in Leaf having a striking resemblance to her moves in Mist should certainly look alarming to him as well, and the argument that we'll need to remove her eventually and it'll only get harder with time should sound convincing too.
But he didn't exactly impress me with his ability to generate creative solutions to tricky problems lately. He might decide to just roll over and die, reasoning that getting suborned by Ami is better than letting Rock destroy Leaf. He might have a lot of possibly-misplaced trust that Naruto wouldn't be so weak/disloyal as to be brainwashed by her (and might get offended at us implying otherwise). He might do a Ren and underestimate Ami in general. He might just tell us to do the contract, commit to handing the clan over to the Hyuuga. (In fact, I think that's exactly what he'll do, unless we omit that part (but then Ami will just tell him on her own). It'd be consistent with what he told us to do WRT Oro.)
And then he'll order us not to attack her, and he'll know we have a motive, and we won't be able to get away with it no matter how well we cover the murder up.
Keeping Hazou ignorant could be achieved by two methods I could think of, and has two obvious benefits and two obvious drawbacks. Methods:
Nudge Mari onto trains of thought that would lead to her re-inventing the plan by having Hazou bring up the relevant points without putting them into the frame of us assassinating her (e. g., we could discuss whether Ami is really as politically untouchable, aren't there any Ren loyalists who'd kill her?). Good assassination strategies are an attractor in concept-space, Mari would doubtlessly think of that approach, it shouldn't be too hard.
Bonus drawback: But it's kind of a blatant metagaming, not sure the QMs would be cool with that. I'm not sure I'm cool with that, it's kinda lame.
TLitF. Vote-in a plan that uploads the assassination scheme into Hazou's mind and has him find Mari at once (ideally, they'd already be in the same room) and ask her to cast TLitF on him. TLitF deletes memories of what happened in it as well as several seconds of memories before that, so Hazou should be able to relay the plan, discuss it, then forget inventing it.
That way, only Mari will know we're responsible, and she could probably beat the Deceit of literally anyone left in Leaf. Hazou won't have to lie to Kei about that, crucially. In addition, an amnesiac!Hazou could be used as bait: he could lure Ami into a prepared location where the assassination could take place (to sign the contract, for example); she'll be less suspicious than she would be if Mari or anyone else did this, since she'd know Hazou wouldn't be able to conceal murderous intent from her — this approach turns her ability to read people and the reliance on it into a fatal flaw.
On the other hand: 1) This prevents us from course-correcting if anything with the plan goes wrong (but Mari could probably be trusted with it, if the core idea is good enough she approves it). 2) It damages Hazou's model of Mari, and prevents us from properly managing her mental state in the aftermath (and it'd doubtlessly be adversely affected, especially in the TLitF route).
One way to get out of the second drawback is to ask Mari to fill us in once everything has blown over and we're unlikely to make anything slip to e. g. Asuma. But she might not.
The Kill Method. Unfettered Brilliance makes it tricky.
I've seen the proposals for just letting Mari handle it by the TLitF+SC combo, and it screams "bad idea" to me. First, Ami might know about TLitF, and she might've devised some countermeasures (possibly FS-derived ones). Worse, it gives Ami a few seconds to react — to realize what's happening and activate Unfettered Brilliance, at which point we'd be facing a high S-ranker. At best, she kills the kill squad before falling into a coma. At worst, she figures out some OCP chakra bullshit way to dodge the consequences entirely, and emerges from the experience more powerful than we could possibly imagine.
She needs to die without a chance to react. I'm thinking arranging for her to sit in some particular chair, then misting her with a well-placed Directional or Implosion Seal through the wall/ceiling/floor.
The crucial thing to ensure here is that nothing within the reach of her senses is causally connected to the assassination attempt. The one luring her in has no idea what's going on. The context of the meeting is whatever we'd do if we weren't assassinating her. The room is a natural choice for said meeting. The furniture isn't rearranged in a conspicuous manner. No-one is looking through the floorboard cracks to see where she is sitting (because if they see her, she may see them). The murder weapon is sitting somewhere beyond her perceptions. And so on. Basically, approach it as if she has Alertness 100.
And then assume something will tip her off anyway, and be ready to deal with that.
Why go to such lengths? Because I think it is only sensible to treat her like she's a fucking in-progress sealing failure.
The Cover-Up.
Article:
[Stealth] wasn't about making sure no one noticed you. It was about making sure that you weren't connected to the narrative in question, making yourself a glittering distraction, waved aside in the pursuit of consequential matters.
We need to arrange it so that when the rest of the world turns to investigate, what they see is a clear, convincing, inevitable-in-retrospect story of how she died, which also has nothing to do with us. It helps that we're mostly perceived as allied to her so closely it verges on treason; Asuma et al. know nothing about her feud with Mari. Only Kei does (and her making the relevant leap of logic is a concern, but we should be able to manage that).
The way to come up with such stories is to ask oneself, "If I learned that Ami died without our involvement, what would I think she died of?". I invite you to ponder that question independently; I'd already anchored myself to my preferred approach.
Hinji Kurosawa, her handler. Ren doubtlessly personally picked him to manage Ami, so he's loyal to her; he's a Kurosawa, duh; so he has plenty of reasons to be Ami's enemy. The news of Ren's downfall at Ami's hand might make him a bit overzealous in his Ami-handling duties, so he might act a bit... rashly. He would be successful, but, regrettably, Ami would manage to get Unfettered Brilliance off in her dying moments, and take him with her. What a tragedy.
On our end: He might be already inclined to do something like that, so we should perhaps scout him out. If not, we plant evidence suggesting he's plotting this — maybe make him suffer some public anti-Ami outburst, maybe frame him for stealing some specific seals. The details of that could probably be left to Mari.
Then we capture him, Mari works on him until he's a barely-coherent automaton just barely capable of following simple instructions, and have him be the one to do the deed during our overengineered assassination. Plausibly we don't even need to do that last part: just kill him, then deposit his body near Ami's, and inflict whatever damage would be consistent with the story we're trying to tell.
As an added bonus, this makes Ami's death an internal Mist matter, driving the risks to the alliance to a minimum. Ami's puppets in Mist don't know what Mari did either yet, they think us allies, they would be looking at Ren or the Hagoromo or something.
The fatal flaw: Hinji might've already left, what with Ami reinstated as the main ambassador. Or perhaps he's still packing, and we need to act quickly.
There are also the two Wakahisa. Remind me of Mist's political situation, were the Wakahisa Ren's allies? I recall they didn't help Ami as we'd asked when she was killboxed, so. They're a worse patsy, but at least we could be sure e. g. our fish guy is still around.
Oh, but this scheme is pretty evil, if you can't tell. For all we know Hinji is an incredibly nice person, and the fish guy is an innocent cinnamon roll by all accounts. But it seems effective.
Another avenue might be Orochimaru: we have plenty to offer him (armor jutsu which he'd really wanted (in fact, the only reason he didn't approach us about them yet might be because he figured we were lying), maybe some of Jiraiya's notes, a voluntary vivisection after all, info on the afterlife if we're really desperate) and Asuma'll just shrug if Oro does that. Drawback: involves interacting with Oro, and while I'm game, I expect to have real trouble getting that voted-in. (Maybe we can indirectly direct his attention Ami's way? She probably won't be able to pull another FGP out of her hat, but who knows. Shit, she might rebound him towards us instead!)
I don't think Naruto or Tsunade are viable options. Naruto for obvious reasons, Tsunade will think the whole matter is ridiculous because Ami is as scary as a kitten to her.
(The ideal way to do that is to, of course, actually make someone else assassinate her, but I'm not sure we have reliable means of making that happen.)
The Aftermath.
I'unno.
If the cover-up goes well, we won't be directly under suspicion, and all we'd need to do is weather Ami's contingencies. She'd doubtlessly already re-aimed some of them at us — both in the sense of inflicting socio-economic damage upon our clan, and "if I'm dead, these people might be responsible" — but it shouldn't be too bad. The material consequences wouldn't be worse than losing Mari (in fact, they might provide opportunities, as most of them should be aimed at e. g. the conservative clans), and the good cover-up + keeping Hazou ignorant should ensure we dodge the responsibility anyway.
I don't think disabling her contingencies is viable. It'd take a lot of time, we definitely won't get all of them, it'd be difficult, it'd be very tricky, it'd definitely tip Ami off, it might trip meta-contingencies that re-aim some of the contingencies to point at whoever is trying to disable them, all kinds of nasty stuff.
I know it may be seen as lame for some of you and I'm not going to try and ruin your plotting fun but when actual voting is going on I would be very hard pressed to vote for anything involving killing Ami, for now at least.

At its most technical, we didn't call her up, she'd have found out eventually anyway and then potentially been angry at us for not telling her, too. We managed to at least not make her take immediate action and nothing terrible happened.

And then he'll order us not to attack her, and he'll know we have a motive, and we won't be able to get away with it no matter how well we cover the murder up.
All I'm saying is, her presence here has political weight (I forget what her exact situation was, again, but you don't kill a jōnin like that) and we should really not believe either that we can pull a sneaky one on the Hokage, or that going behind the tails backs of our superiors is a good idea.
Asuma isn't forced to think of acting against an allied S-ranker with no time to prepare here - this is a threat to go either after a Leaf jōnin or a Leaf clan and this will not do, but he has several advisors that may or may not be secret, access to more information than us, and we desperately need to be in his good books for realsies.
Best case scenario he takes care of it, which means we don't have to. Worst case scenario we probably will get some kind of help nonetheless. One does not walk into Leaf and threaten its people.
At its most technical, we didn't call her up, she'd have found out eventually anyway and then potentially been angry at us for not telling her, too. We managed to at least not make her take immediate action and nothing terrible happened.
Oh, but we did. I did, even. I'm referring to that first date in Mist, way back when. We contacted her, we brought her into Hazou's story, we pushed for her to stop distancing herself from Kei. On a meta-level, we gave her narrative importance by focusing on her so much. If not for us, she'd have no reason to go to Leaf. She'd be still be in Mist, distant, plotting. (I'm joking here, I'm not actually regretful about any of that.)

Why can't we pull a sneaky one on the Hokage? Ami certainly thinks she can, and the only reason we didn't manage to with the Akatsuki that one time was because of Haru. As long as we keep good information hygiene, I don't see why it's so impossible. We don't even have a motive Asuma is aware of!
One does not walk into Leaf and threaten its people.
... Yes one does? Orochimaru surely did that pretty well, and even actually non-consensually vivisected some of them if Ami is to be believed. And she certainly seems to think she has a similar level of protection, so I don't see why not. And again, Ami's "sign a contract to hand all of your assets off to the Hyuuga if I say so, and I won't do anything" is a pretty good deal to him.

Ami is a lot better than us at many things, and in the core of Leaf Hazō is constantly surprised by how many people know things he didn't plan for them to learn (his Gōketsu speeches being shared outside), or didn't know about (Haru killing Yakuza). Everyone important has ears everywhere and we only ever trained to deal with the literal, Kozu kind. If it gets out at any date in the future that we did this kind of thing we're in trouble. If we fail and we didn't have Hokage support we're in doubleshit hell

This seems like a redundant concern. I mean, we could probably figure out a way to kill her because the Gouketsu are really good at killing things, but also not exactly subtle about it and killing The Ami would probably involve fireballs visible from orbit, at which point Asuma wouldn't have to do anything because Kei and the KEI and Mist and the entire ISC would be out for blood. At that point the best option left would be making a beeline for finding out what the southern hemisphere looks like.

She needs to die without a chance to react. I'm thinking arranging for her to sit in some particular chair, then misting her with a well-placed Directional or Implosion Seal through the wall/ceiling/floor.
The crucial thing to ensure here is that nothing within the reach of her senses is causally connected to the assassination attempt. The one luring her in has no idea what's going on. The context of the meeting is whatever we'd do if we weren't assassinating her. The room is a natural choice for said meeting. The furniture isn't rearranged in a conspicuous manner. No-one is looking through the floorboard cracks to see where she is sitting (because if they see her, she may see them). The murder weapon is sitting somewhere beyond her perceptions. And so on. Basically, approach it as if she has Alertness 100.
And then assume something will tip her off anyway, and be ready to deal with that.
Why go to such lengths? Because I think it is only sensible to treat her like she's a fucking in-progress sealing failure.
The Cover-Up.
Article:
[Stealth] wasn't about making sure no one noticed you. It was about making sure that you weren't connected to the narrative in question, making yourself a glittering distraction, waved aside in the pursuit of consequential matters.
We need to arrange it so that when the rest of the world turns to investigate, what they see is a clear, convincing, inevitable-in-retrospect story of how she died, which also has nothing to do with us. It helps that we're mostly perceived as allied to her so closely it verges on treason; Asuma et al. know nothing about her feud with Mari. Only Kei does (and her making the relevant leap of logic is a concern, but we should be able to manage that).
The way to come up with such stories is to ask oneself, "If I learned that Ami died without our involvement, what would I think she died of?". I invite you to ponder that question independently; I'd already anchored myself to my preferred approach.
Hinji Kurosawa, her handler. Ren doubtlessly personally picked him to manage Ami, so he's loyal to her; he's a Kurosawa, duh; so he has plenty of reasons to be Ami's enemy. The news of Ren's downfall at Ami's hand might make him a bit overzealous in his Ami-handling duties, so he might act a bit... rashly. He would be successful, but, regrettably, Ami would manage to get Unfettered Brilliance off in her dying moments, and take him with her. What a tragedy.
On our end: He might be already inclined to do something like that, so we should perhaps scout him out. If not, we plant evidence suggesting he's plotting this — maybe make him suffer some public anti-Ami outburst, maybe frame him for stealing some specific seals. The details of that could probably be left to Mari.
Then we capture him, Mari works on him until he's a barely-coherent automaton just barely capable of following simple instructions, and have him be the one to do the deed during our overengineered assassination. Plausibly we don't even need to do that last part: just kill him, then deposit his body near Ami's, and inflict whatever damage would be consistent with the story we're trying to tell.
As an added bonus, this makes Ami's death an internal Mist matter, driving the risks to the alliance to a minimum. Ami's puppets in Mist don't know what Mari did either yet, they think us allies, they would be looking at Ren or the Hagoromo or something.
The fatal flaw: Hinji might've already left, what with Ami reinstated as the main ambassador. Or perhaps he's still packing, and we need to act quickly.
There are also the two Wakahisa. Remind me of Mist's political situation, were the Wakahisa Ren's allies? I recall they didn't help Ami as we'd asked when she was killboxed, so. They're a worse patsy, but at least we could be sure e. g. our fish guy is still around.
Oh, but this scheme is pretty evil, if you can't tell. For all we know Hinji is an incredibly nice person, and the fish guy is an innocent cinnamon roll by all accounts. But it seems effective.
Another avenue might be Orochimaru: we have plenty to offer him (armor jutsu which he'd really wanted (in fact, the only reason he didn't approach us about them yet might be because he figured we were lying), maybe some of Jiraiya's notes, a voluntary vivisection after all, info on the afterlife if we're really desperate) and Asuma'll just shrug if Oro does that. Drawback: involves interacting with Oro, and while I'm game, I expect to have real trouble getting that voted-in. (Maybe we can indirectly direct his attention Ami's way? She probably won't be able to pull another FGP out of her hat, but who knows. Shit, she might rebound him towards us instead!)
I don't think Naruto or Tsunade are viable options. Naruto for obvious reasons, Tsunade will think the whole matter is ridiculous because Ami is as scary as a kitten to her.
(The ideal way to do that is to, of course, actually make someone else assassinate her, but I'm not sure we have reliable means of making that happen.)
The Aftermath.
I'unno.
If the cover-up goes well, we won't be directly under suspicion, and all we'd need to do is weather Ami's contingencies. She'd doubtlessly already re-aimed some of them at us — both in the sense of inflicting socio-economic damage upon our clan, and "if I'm dead, these people might be responsible" — but it shouldn't be too bad. The material consequences wouldn't be worse than losing Mari (in fact, they might provide opportunities, as most of them should be aimed at e. g. the conservative clans), and the good cover-up + keeping Hazou ignorant should ensure we dodge the responsibility anyway.
I don't think disabling her contingencies is viable. It'd take a lot of time, we definitely won't get all of them, it'd be difficult, it'd be very tricky, it'd definitely tip Ami off, it might trip meta-contingencies that re-aim some of the contingencies to point at whoever is trying to disable them, all kinds of nasty stuff.
Actually, what if we mentioned to snuncle everything we know and suspect about the five thinker clans. Seems like something he'd be interested in vivisecting investigating. He swore to Tsunade not to harm Leaf citizens, but Ami is a Mist citizen. Plus, we have well-established reason to try to stay on his good side for Kei's safety. Well-intentioned mistake with dramatic consequences? Nah, that seems out of character for Hazou.
