5. Avengers: Disassembled

I mean, there's always this one.

If you want to reboot your Avengers team for a new generation, you can always adapt the comic that did that exact thing.

Scarlet Witch loses control of her powers in Avengers: Disassembled, and that sets off a chain of horrific events that kill half of the Avengers lineup and disillusions many of those who survive. In the aftermath, a group of heroes who responded to a prison break at the Raft band together to form a new team of Avengers. They keep Cap and Iron Man (the MCU probably wouldn't), and add Spider-Man (likely), Spider-Woman (maybe), Luke Cage (never gonna happen, sadly), and Wolverine. And if you want to bring X-Men characters into the MCU, it would be smart to begin by adding just one or two. And the obvious starting point is obvious.

This would be a good way to kick off a new MCU era, but Scarlet Witch would be wasted as a character, and that would kinda suck. Also, if they follow the storyline from the comics and kill off Scott Lang, I'll be endlessly pissed off.
