Not that it's likely to happen but the Wasp might be doable. That world (more so that Wakanda) would make for an interesting darkride especially if Imagineering were able to create the same "Honey I shrunk the Kids" ant point of view with everything in massive scale. A change in perspective worked for Peter Pan's Flight. Not sure if "The Wasp" is an original Avenger or not but as has been discussed, using secondary characters and unique surroundings might be enough for development of a ride or attraction assuming it bypasses any contractual restraints. Still pretty unlikely though.
While not an original, The Wasp was at one time the leader of the Avengers. And with her close relation to Ant-Man (tech-wise and personally), she would certainly be in "the family" of what's excluded.
