Wasn't sure if this was worthy of a new thread (being just a rumor), but Screamscape is reporting that a Hyperspace Mountain style overlay may be in the works for RnR to add more Star Wars quickly.
I know a lot of people discount Screamscape's news and rumors, but sometimes they are right (even a stopped clock is right twice a day!), and while I haven't heard this from any of my Disney sources, once again it fits the pattern that Disney seems to be getting into of quick (relatively) cheap makeovers to existing attractions to counter the competition's new offerings and capitalize on hot properties.
I'm not sure how this would work since I'd guess there are contractual obligations for Aerosmith and what they can or cannot do. It does make sense they might try something like this to keep people coming to DHS for the next few (3-5) years while the rest of the park is a construction zone, but taking one of the few major attraction off-line for a makeover may be tricky.
