Don't Take Toffee's Deal
Bear in mind that a lot of quest actions have DCs of, like, 80 or more. Having a combined bonus in the 30s is not reassuring.
The extreme Martial makes it likely that we can survive any direct fights we get into, but Occult rolls can result in serious injuries, and blowing a Diplomacy or Stewardship check can cause other complications.
Why not just... take Chicken Itza first...?
Because I don't think it will help?
Your reasoning for why it would appeared to be that it would make Felldrake help us more.
My counterargument was that he won't help us with the map in general, but he's fine with us sending him to Xanadu and once he's there he's not going to get his bearer killed. So, if we wanted to appreciably boost our odds, we would need to shake free our A-Tier questing unit, Russ, from the high-DC and clearly important Intrigue actions.
(Also, again. Chicken Itza and Acme is mutually exclusive with Acme and Social Media, and I would like to not allow ENCOM to further entrench its dominance while also doing literally nothing to defend ourselves in the PR war. Not panicking about PR, yes, literally nothing, no.)
I don't think so. Felldrake would probably identify the artifacts as apart of being the guy in charge of the excavation. This is his temple after all.
Knowing more about the other places on the map will help us judge Xanadu.
Fair enough, we might get lucky on some of those artifacts. We might not, but we might. I'm just not sure what sort of transformative upgrade you expect to find in the loot pile.
As for the map helpind us judge Xanadu - judge it how? We're already extremely spooked, because it holds mystery sealed mythological beasts. Unless you think it'll ease our concerns, which should make us more willing to go in without Russ, I'm not sure what you're expecting to find.
Plus, as we've seen, even with a -10 to all DCs, many DCs can still be over a hundred... including the Peru one. So without a high Stewardship person on the team, they may not even be able to find the place. Heck, the trek there may have a DC over a hundred itself, meaning we'd need to roll ridiculously high to actually succeed.
Wile E. Coyote is in high demand both as a Stewardship Hero and Acme connection right now, but if we shook him free he'd give us a comparative +8 over Max (with Janna). It's not nothing, sure, but I'm not sure it's enough to justify yoinking him now that we're doing two Stewardship national actions per turn.
Because that's another point - with two actions per turn in most categories, it is harder for us to spare heroes for quests, since there are nationally important actions we could have them do instead.
Especially since we shouldn't assume we need to succeed at every roll we come across in the first place. The first half of Birds of a Feather was a complete clown fiesta, and that still ended well. With less Toon Force in the air, I don't see a Stewardship failures doing us in. (Especially if Khan can parlay being Genghis Khan into a bonus on finding a guide for the Diplo check. I've heard less plausible things.)
And one of the most dangerous ways failure can get to us is through traps or monsters or what have you, and again - 97 Martial forgives many sins.
