The separation masters could be used to make a very good looking Blu-Ray. Not quite as good as going back to o-neg would, of course, but you'd be surprised at how few Blu-Ray releases actually do go back to o-neg. Most are transferred from interpositives.

Given that scanning the negative does not allow direct use of the original colour timing, interpositives make a good deal of sense as a source. Though with fading, that would tend to be less useful than it might at first seem, particularly in this case.

I've always wondered about the separation masters ever since I heard that such a thing existed. I haven't heard that they actually bothered to use them for the '97 SE, using interpositive material instead to replace badly damaged sections. That makes it seem very unlikely they'd go to the effort for the version that GL himself is embarrassed by, even if he ever agreed to do them. Still, at least they exist somewhere for a future restoration effort far down the line, whenever that is finally able to happen.
