It is a big deal to Disney Jim was an iconic figure they leave it as a tribute. I know for a fact that there are no plans to remove it so don't hold your breath. Also you will never see a WIR attraction unless the 2nd film does better than the first.
What scene or scenes would you replace and what would you replace it with.
I would get rid of Foot light Parade and replace it with The Jazz Singer. It has much more significance in film history.
Tarzan would be replaced by Star Wars Empire Strikes back Light saber duel.
