I just watched some videos of the original. It really holds up really, really well story wise. If they ever were going to recreate a classic, this would be it for WDW. Using today's technology with the original ride would be a slam dunk, especially given the love for Figment.
They could even change the turn table into a pre-show or something to get around that hurdle - since you could easily queue and board in the DreamPort scene, picking up the ride from there.
I don't delude myself to believe it's true. But, it really could be such an amazing way of reaching out to the Figment and Epcot fanbase in a way I think many people would love.
