I think a simple IP sourced disc would look great and feel very authentic. But one thing that doesn't come up often is the YCM separation masters. When Lucas did the interview with Christopher Nolan, he said the cyan layer was out of sync so they were no help. But he was talking about using it as a source for a theatrical rerelease in 1996. Can't they correct for that fairly easily now? The criterion HEAVEN'S GATE used separation masters because the negative had been cut to the short version, and it looks great.
