After reading the blu-ray article, playing the devil's advocate a bit (I think that's the phrase, english is not my first language). Is it possible that what Luca$ refers to as the "classic version" is a version without the slightest change?? What I'm talking about is stuff like the Battle of Hoth, the Rancor scene, the Speeder Bike chase, all the stuff that had elements re-composited, and maybe that's why he says it would be expensive??
Because what zombie is talking about is just cleaning up the discarded stuff like the original Mos Eisley, but in reality there were a lot more changes.
