I think Epcot's futureworld, and this will probably ruffle some feathers, needs to ditch the whole "future" theme. Disney is not capable of keeping up with "the future". Tomorrowland only works in that nostalgic 50's style retro-future way. But it wasn't always meant to be that way. Tomorrowland at
Disneyland was much more "Epcot" in that it featured companies like Monsanto and DOW coming in and setting up exhibits that were supposed to "wow" people with the how their lives were about the change. At some point the "future" came and went, and it looked nothing like tomorrowland anymore. While they made a few attempts to update it (mission to the moon becomes mission to mars, etc), eventually it seems they realized that the 50's future was the safest and easiest thing to do.
Everything "futuristic" that Disney has ever tried to do has rotted out. Look at DisneyQuest for example. They simply couldn't keep that place up to date, so they didn't even try.
Epcot's futurworld is full of outdated sillyness, empty halls, and one massive gift shop. In keeping with SpaceShip earth and the somewhat educational theme of Epcot, ditching the "future" aspect and simply going with a technology or even historical technoloy theme makes the most sense.
That said, I don't think Star Wars fits there at all. DHS was always supposed to be about movies. The Disney Company never seemed to really understand if they wanted to compete with universal and do a "behind the scnees" experience or follow their previous parks and create an imaginary world to live in, and that schizophrenic approach to the park did them no favors. I always felt as though they belt the park to be a behind the scenes experience, but then ran it as though it was it's own fantasy world that you were supposed to 'buy into'. After all, why have all their other parks designed to submerse you in magic simply to have one that gives up all the secrets.
Anyways, back on topic, I've always felt that a Muppet Dinner Theater would be the perfect use of the IP. You simply can't put people in muppets costumes and have them walk around and retain any of what makes them muppets. Which severely limits the public's interaction with them. But a dinner theater with animatronics is right up Disney's alley. Heck, have the main "host" (Kermit presumably) run by an actual puppeteer. Either way, the muppets home is a theater. Imagine getting to eat dinner while hearing the opening theme to the Muppet Show playing, seeing all the muppets singing along, and having that curtain come up and feeling as though you are right there in the audience for one of their original shows. While I'm obviously in the minority, I'd book a trip to Disney just for that.
