Instead of getting hung up on the term "original", most people would probably be satisfied with an up resolution version of the film that was releases as the old VHS home video releases or the THX remastered sound releases from before the Special Edition was made.
I’d be happy with that.
I’d be ecstatic with a well-within-the-bounds-of-technology-and-reason-but-might-be-very-pricey set with all of the different video and audio versions of the film utilizing seamless branching. Might cost upwards of $50 a movie, but I’d definitely do it.
