What if the cast reveal happened during the filming of thunderbolts post credits scene since an interview confirmed that it was shot for doomsday.
What if the cast named was for the first act of the film in a set piece ala the Wakanda battle from infinity war but instead this is in the x Mansion according to the tease.
Professor X and Magneto being reluctant Allies along with cyclops, mystique and nightcrawler along with maybe beast being the one to get gambit from the void.
Meanwhile the new avengers aka Yelena, red guardian, us agent, ghost, Bucky and sentry work with the fantastic four to follow doom who went into the x mansion.
Then after the new avengers and fantastic four are nearly finished off by doom, cap ala like Steve from infinity war save them with Shang chi, falcon, Thor, tic tac aka ant man, and Wakanda Allies like Shuri and M’Baku and even Namor. Also we get see Loki watch from distance.
