Since wiping each other out or pulling a Red Wedding at Tony&Emma’s nuptials is a no-no, I suppose the only fundamental change left is for Krakoa to replace Wakanda as the Avengers backer and for the Avengers to be working for the X-Men
While interesting in theory, there’s any number of RL reasons it’s not going to end in anything but disaster
Even if Aaron’s run was done, and the signs do point to it being in something akin to the home run; there would still be issues
The main Marvel office would have to be surrendering control of the Avengers books and the control that would effect said characters solo books, otherwise the editorial squabbles would cause another UA. And that’s both unlikely, and probably bad business decision, as I don’t see the guy who carried out a palace coup against Hickman being the guy who’d make sure to curate the Avengers title alongside the X-Men
So...is this a three-way war or do the Avengers and X-Men end up teaming-up against the Eternals?
I get that it makes sense from the perspective of Gillen's current storyline but it seems kind of weird to be pairing the latest hot IP you're pushing (even if the movie didn't do as well as you'd hope) against your two other biggest IP's.
(Then again Shang-Chi just went up against a bunch of heroes in his new series...).
I think it starts as a three-way before the Avengers and X-Men team-up to take on the Eternals. What's interesting is that Thanos currently leads the Eternals, other than those who fled to live with the Deviants.
The Eternals want their Celestial god back from the Avengers who currently call it home and then there is the issue of resurrections and what the Eternals learned about their process. They could have an issue with mutant resurrections.
