I wonder what it would have been like if he had done the changes back during 78-82, since the movie was being re-released every year anyway, it must have crossed his mind. Especially since Spielberg did exactly that with Close Encounters, right down to the "special edition" tag. He even had access to the still age-appropriate actors (Spielberg brought back Dreyfuss and Bob Balaban 3 years later) and was apparently so tortured and emo about the shots that didn't work, he might have done something interesting.

IIRC, it was the studio that pressured Steven to add the inside of the mothership scene in order to greenlight spending the extra dough on the other changes. He's recut the film a few more times since then, and the mothership interior was omitted.

If George really was unhappy with the Greedo scene back in the day, (or even the other parts of the Cantina scenes) the Holiday Special production would have been a perfect opportunity to go back and reshoot it.
