I dont think star tours needs to be removed, just rethemed. The building is fine, the ride itself is fine but a new experience would be amazing. I really wonder if they couldnt use it as a black box.
First Im a huge star wars fan but now with galaxys edge, star tours is an empty walkon most times.
Why not remove all the star wars branding, send the ATAT to my house for display, then make the queue all about disney history or do like disneylands mickeys runaway railroad, you could also show movie props ala great movie ride.
The ride itself would be a black box, no characters or anything and your safety spiel would introduce you to classic disney and classic hollywood. Then the attraction starts, you dont know what movie you will be in but they could use the randomizer to change it every ride.
This would give movies like chitty chitty bang bang, walle, fox and the hound, bambi, roger rabbit, the rescuers a place in the park and something completely new.. you could randomize 2 or 3 adventures or one really long one, and maybe you start out with 20 different ones and add new ones every year.
