Captain America 4: The Time Traveler

I think it would be epic if they did one more Captain America movie that showed what all Cap did when he went back to return the stones(like how he ended up marrying Peggy and if they had any kids, and when exactly he retired). And then the end of the movie should be the scene from Endgame where he comes back to 2023 at the exact moment that young Steve/Cap is going back to return the stones and sits on the bench until Hulk, Bucky, and Sam notice him sitting there.
