^ I've never heard the filmmakers had any misgivings about Shia at the time of the movie's release. Ford mainly just loves the character (IIRC, there were rumors he agreed to do
The Force Awakens in part because they promised him one last Indy go-round), and I don't think anyone at Disney has yet talked about any replacement.
Anyhow, I had an idea for a hand-off a while back I thought was pretty darn cool, if I may say so myself; and here it is:
------------------------
At the risk of ripping off an idea from
The Last Crusade, how about: the opening sequence features a new, recast young Indy. He has a thrilling adventure scene, but then is about to be captured - how will he possibly escape?! Cut to the present, and Indy is telling Marion/Mutt/whoever the tale when he's interrupted by an urgent visitor who sets the plot in motion, a plot which coincidentally has to do with the thing the young Indy was chasing in that very story. The movie happens.
Then, in the final scene, as they're relaxing around the fireplace, Marion/Mutt/whoever says "by the way, just how did you survive that certain death from the opening sequence?" Ford grins, says, "that's a funny story"; we cut back to the past and the young Indy, something surprising happens, and -
CREDITS, with the next movie following said young Indy, picking up right where the story left off.
