go back and watch your ANH video (specifically, the GL interview at the beginning). GL says that they had an actor stand in and read the lines (like he always does), and that they were going to go back later and replace the actor with a creature.
so i think that he was just being sarcastic. i don't think that GL ever had a human jabba in mind. early conceptual drawings of jabba even look a little hairy like chewie.
The SE were ok but some of the changes were unnecessary.....I kinda liked the Ewok's celebration at the end of RotJ. 😄
