I'd hire Robert Harris to go back to the original negatives or whatever the best usable prints are and restore the trilogy to exactly the way they were in 1977, 1980, and 1983.

Then I'd hand over the restored elements to someone who is passionate about the project and wouldn't release anything half assed to supervise the creation the Special Edition versions, staying as true as possible to the original intentions of the filmmakers and artists. Also keep some key members of the crew (art & set decorators, costume designers, cameramen, editors, sound designers) on hand for their opinions/approval. Lucas ultimately will have final approval, but whoever takes the job of supervising the project will have to be able to stand up to the guy and make Lucas realize when his ideas are stupid.

Then go all out on the DVD extras and give the movies as much love as they deserve.
