A way to understand Lucasfilm's stance on this issue is to ask their Public Relations person (ok Sansweet, where does he show up next?) if LFL's view this bluray set as a complete collection or archival. (prefer the archival terminology over complete collection, but that's just me) If the response is 'No' then this campaign needs to really crank up public awareness, since the no response would lead me to believe this is a commercial venture as the DVDs originally were.
With the 2 active SW independent productions currently active (PvsG and SWUncut) that provides an easy audience to tap into to. (especially online) Conceptually PvsG is onboard, so they'd likely give this idea free press.
But I wouldn't contact them until it's figure out the stance everyone's comfortable with. When people say 'Original Theatrical Version*' a detail description should be available at the '*'. For Star Wars 77, does that include 70mm & 35mm audio? Is a crawl without Episode IV a sticking point? For TPM does that include the differences between theatrical film and the early digital projection? Does Maul not getting cut in half, be part of this list? (Please bring up all the other variations) Including the PT changes will help this cause, it'll show that it's not just OT fans wanting their 'the way we remember it' movies, but that as a group we believe in having documented proof of what we did see. Plus pulling in the PT generation to introduce them into the concept of proper and complete preservation, can't hurt.
