I mean. I disagree. It doesn't sound that hard. We've accidentally managed it already without time travel. But even on that extreme we already kinda did? Time runes are a thing? We've already been shown to have the ability to manipulate time.
Hazo seems to think it is possible, but it will take a lot of work.
We're capable of making a region move forward in time at a faster. We haven't done anything that could send someone backwards in time. If you want to equivocate the two then be my guest, but they aren't the same thing.
I feel the brief need to mention that if we wish to save Jiraiya and Akane we do not in fact have all the time in the world, but setting that aside:
I don't know enough about the Rinengan to say. My point was just because Hazo personally can't do X doesn't mean we can't do X. We can get help. It's not a solo project. And according to google, more than one person's gotten the Rinnegan in canon. Can't you just combine Hagoromo DNA with Uchila's lineage? Dunno. Even if the rinengan is out of reach or very hard, I'm not to worried or hung up about it.
I dunno. My argument isn't really focused on any specific path here.
Sounds fine? If we beat Akasuki, and are bored to continue, we can just have an epilogue where we finally reunite with Akane and jiraya after years of research. That's still a win in my book.
I dunno. My reason to believe this is both the setting says it should be possible and it's been done before. And the meta reason, of we're playing a quest, for fun, with QMs, who are people and it would be lame and boring if it was literaly impossible by fiat. There's been no indication from the setting that it would impossible to replicate except your paranoia and risk aversion. Will it be Hard? Almost certainly. Impossible? Why would it be? It wouldn't be good game design. You forget, we are the protagonist and the setting (within reason) does actually (somewhat/marginally) bend over backwards to entertain us. We've been told outside the quest that seals actually do have the power to theoretically do anything. (The seals might be to hard for us to research, but meh) And the QMs have said if we're clever enough and go far enough in this quest we'll be allowed to become literal gods in this settings and rewrite the world completly toward Uplift (or our dreams). Why start doubting now, anon?
My response is Mu: We will not live to see a world in which Akatsuki gets to make it through the rift and back. So there's little reason to worry about it.
This is broadly consistent with my own analysis. I think there's even a distinct possibility Nagato/Pain could be better for the world than Pax Konoha, albeit likely worse for Hazo personally and his known allies. Looks bad based on the kind of people he recruited, but how many previously-unaligned S-rankers were available to choose from?
This suggestion is a plot by the cake industry to increase sales. Don't fall for it !

Another thought: do people age in the afterlife? HDK but, if not then Akane will come out as the 16 (I think?) year old girl that she was when she went in. That's a problem if it takes 3 or 5 or 10 biological years for Hazō to rescue her.
I think this fell through the cracks, so thank you for the bump. We'll talk it over and get back to you.
What is 'age', at a certain point, other than an arbitrary biological marker? I want to stay as far away as possible from 'age ain't nothing but a number' arguments, but if we count age as a function of "amount of time consumed to accumulate life experiences" I would posit that any time you spend conscious contributes to your age, regardless of the physiological effects that time has on the body. (This is, of course, not accounting for puberty and other time-entropy-based physical conditions)
It's my understanding that a person's life experiences, aka their memories, are reduced the longer one spends in the afterlife.
I think that "not accounting for puberty" is doing a lot of work for you there. After about 25 or so, if we solved biological immortality, age would indeed just represent life experience. Before then, there are major neurological changes going on that life experience would not replicate. Proper risk assessment, adult executive function and emotional processing, and so on are things you get from brain development, not just life experience. So the relevance of age to e.g. "appropriateness of having a romantic relationship with someone" should be primarily driven by biological age rather than chronological age, at least up to about 25 or so - and since Akane is 16, the question of whether people age in the afterlife would be very relevant to her!
Well, my broader point was that if they were conscious in the Pure Lands, that should count as some kind of 'time served' in regards to aging, but the Pure Lands removing memories does contravene that. Still, it feels prudent to point out that the 25 number for brain aging isn't actually a thing. But by all means, Akane is probably going to be suffering from a lot of knock-on effects from being dead for however long until we rescue her.
Fair - I hadn't investigated the 25 number in detail, it's just what my brain spat out as a "this is roughly where development peaks give or take five years", but you're right that a brief look suggests that it's more complex than that. The key point was that 16 is definitely young enough that there still is major brain development going on that may or may not continue in the Pure Lands.
That doesn't sound like he was fully aware before we reached out to him - it sounds like he was reliving old memories, not accumulating new experiences. Which makes sense - if people were fully aware in the afterlife, even only during the time while their memories were being stripped away, we'd expect there to be some kind of civilization, and we saw no sign of that. We might not have done, of course - if you picked a random location in the EN to open a rift into you probably wouldn't see much sign of civilisation there either - but lots of sealmasters have died and would have kept their chakra long enough to some of them to decide to start randomly causing sealing failures and seeing what happens, and we didn't see evidence of that either.
So you're saying we'll be have it figured out within five years tops, got it.
We'd need biosealing, I think? This is IMO the biggest problem with the lighthouse-for-years plan; we don't have biosealing and we don't have anyone who can teach us it, so we're stuck in mortal human bodies when we could be using our Kage-level sealing stat to reshape our flesh into something greater. We have the potential to be better at biosealing than Orochimaru, if only we could find someone to get us started.
I see your explainer article in Science Focus and raise you a peer-reviewed article in PubMed: Maturation of the adolescent brain - PMC.
Article: It is well established that the brain undergoes a "rewiring" process that is not complete until approximately 25 years of age.5 This discovery has enhanced our basic understanding regarding adolescent brain maturation and it has provided support for behaviors experienced in late adolescence and early adulthood. Several investigators consider the age span 10–24 years as adolescence[...]

The development and maturation of the prefrontal cortex occurs primarily during adolescence and is fully accomplished at the age of 25 years. The development of the prefrontal cortex is very important for complex behavioral performance, as this region of the brain helps accomplish executive brain functions.

I glanced over your linked studies but didn't see the participant's ages. The point @Spector29 was making is that the first studies that established this magic age 25 for stoppage of rewiring that these linked studies cite over and over, only studied people up to age 25.I see your explainer article in Science Focus and raise you a peer-reviewed article in PubMed: Maturation of the adolescent brain - PMC.

And a second option, one of many cited from that paper although I only took the time to read the first one in detail:

Short answer: yes, large-scale brain development throughout adolescence is a thing, yes "adolescence" has fuzzy boundaries, yes age 25 is a reasonable cutoff for the end of adolescence.
