I think they should have gotten a new Indy and continued with the original time-frame. Have Ford play a cameo or something. It was time to pass the baton.
Oh my goodness, NO! The thing I was worried about the most with KOTCS is if Ford could still be a good Indy. Turns out he can be and was the best part of the movie. I just hope they do a fifth because, to me, Indy movies seem to have reverse-Star Trek disease. The odd number ones are the best.
