Hell yes!
Absolutely!
Either a 3-hour slugfest or a 2-parter like Infinity War/Endgame. With Cap as the hero and Scott as the misguided-but-good-intentioned Magneto-style anti-hero.
Honestly, if/when Marvel Studios does AvX, I hope they scrap the plot of the comics version entirely, and come up with an original story. A villain manipulates the Avengers and the X-Men into fighting each other followed by the two teams working together to take the villain down. Or something. Anything but the character derailing shitshow that was the comics version.
If Marvel ever does AvX, it'll be Cyclops vs either Carol or T'Challa, since Cap will already be gone.

There's a case to be made that IvX is THE worst event in Marvel. Made no sense at the time, made less sense when they tried to rationalize it, explanations made it worse, talks with the editor made it MUCH worse ("peanut allergy"), and overall sits like a poisonous toad on top of the Marvel continuity chart.
