Just asking since there seems to be no way we could get Ironman 4.
I would think its possible to have something done in the Captain Marvel movies sort of like how Winter Soldier and Falcon along with everything from Civil War kind of took a life of its own. Hell I'd say that Captain America Civil War was really an Avengers movie for all the different things it kicked off and that spun out of it like even Bkack Panther.
So im just thinking of the whole Arno Stark thing. Him becoming the new Ironman but his whole origin with the Kree and 451 whatever could be an interesting tie in to a Captain Marvel movie. There could be alot of different ways to go the whole thing or maybe it could actually just be Ironman 4. Either way I think the Arno Stark story would make for some good stuff either in movies or a tv show
