Ok, if no one minds me starting the ball rolling on the organizational end of this, I'd say that the first order of business is the clean-up of the ride film itself, as posted on the torrents at Mousebits.com... as mentioned above, it has some bad color issues (yellow Star Destroyers), etc.
Who here is up to the task of color-correcting it? I have to sit this process out, as I myself am color-blind, so I've never really looked into software that could aid in such a project.
I've got some reference photos that might prove handy for this project. Not just of the repurposed Star Destroyer filming models, but some books (Chronicles et al.) have published photos of the StarSpeeder filming model built by Ira Keeler, as well as the launch tunnel set built by Steve Gawley, which was redressed to become the crash-landing set.
While a harsh flash photograph is not always the best indicator of 'show lighting' or moody film lighting, these pics should still help with some color decisions.
