Personally I would be more happy to see someone take a stab at the pre-THX LD transfers instead, but every attempt to get the films colortiming closer to its original state is always welcomed. :)
I'm glad to see that my sub-script coming to good use, don't feel restricted by it though, it's not perfect IMO, I would be happy to see someone improve upon it.
As this is mainly a color correction project, I suggest that you keep these glitches in mind: http://originaltrilogy.com/forum/topic.cfm/Star-Wars-Trilogy-Original-Theatrical-Versions-2006-DVD-Flaw-List/post/462787/#TopicPost462787
Maybe you could splice in footage from other sources in those scenes.
The close up of the twin suns should also be red in color and not blue/purple as you can see in this post for example: http://originaltrilogy.com/forum/topic.cfm/Star-Wars-Colortiming-Cinematography-was-What-changes-was-done-to-STAR-WARS-in-93/post/428819/#TopicPost428819
That is something I'm 100% sure of as I've obsessively studied that close up on many transfers out there, and that close up is only blue/purple in the '93 telecine.
I'm looking forward to see what you can accomplish, good luck with this project.
