The point of franchise heroes (whether super- or otherwise) is that audiences buy into that persona, and they sure as hell don't want to see it changed (hence the lack of an actual personality-altering character arc for franchise heroes like James Bond or Indiana Jones).
Tony settling down in a more serious relationship is maturing. Tony seeing his father in a different light is maturing. This is currently happening in this franchise.
Indiana Jones sort of proves my point, because the character is stuck in the 40's-60's and he ages accordingly, dating back to the young Indiana Jones TV series. He is not updated to fit a future era. That is how I see this franchise playing out. Not like Bond where they are telling a new story/take on the character every time.
