Okay, I can see it being Cho and I'm on board for that.
Legacy characters CAN make sense. Cap, to me, does. It's a symbol. Sam is a DIFFERENT Cap, but it still MEANS the same thing. Iron Man is a piece of technology. It was developed to save Tony's life, but it's something else now. Spider-Man works because alternate reality. But Thor and Hulk? I don't get it. Those don't "work" within the confines of the character. Not to me.
