As much as a 3.0 would actually be great using a 35mm scan, i'm sort of missing the point here, why would he need to despecialise that.. isn't it already the theatrical cut of Star Wars pre-97?
Also, rather than a million edits of Star Wars, i'd rather see a new ESB & ROTJ to complete the trilogy personally, it's your project though so I can't force you, haha.
