I'd be satisfied with the major variants on a branching DVD.

Both '77 and '79 versions of Star Wars with multiple audio tracks on the same blu-ray.

I'm sure you meant the '81 re-release with the revised opening, '79 was just a theatrical re-release of the original film.

I agree with Sluggo, just keep it simple:

1977 Star Wars, with the three original audio mixes and a possible branching for the revised '81 opening.

1980 Empire, with the two original audio mixes and a possible branching for the early 70mm cut.

1983 Jedi, with the two original audio mixes.
