solo movies and Avengers simultanously, both in the present.

Cap has a life outside of the Avengers in the present that is much more compelling than a period piece sequel would be. He has his own cast of characters that fans love, and would want to see in sequels; the period piece lacks that cast.

I wouldn't kill off Cap. I would actually kill off Sharon Carter, and have Cap retire due to that (movie cap doesn't have to be like comic cap, who would keep on being Cap just because.) Then I would have Bucky take over.
