Nevermind that Miles is half-Latino and there aren't any Latinos onscreen.
Yeah I think when he's introduced it will be pretty popular.
As for Steve Rogers, eventually the MCU is going to at least move on from the founders if not replace them with legacy characters. Probably just replace them with new ones, a Cap Marvel maybe swapped in?
