oh and yeah, a lot of old ideas were re-used for the PT, as is evident in the title of Revenge of the sith which was originally Revenge of the Jedi for the OT but was changed. So we can see where lucas got the idea for that. Also some planets and such were around from the first draft of star wars, I think. Unfortunately his CGI obsession overtook his better judgment and he went crazy with it.
Anyway it won't work no matter how you spin and twist it, the two trilogies will never be one or else Vader might dance over to his old droid pal and reminise over the good ol days when his head was swapped with a battle droid's, oh it was such a drag. Oh don't even get me started on Obi-wan's problems. GL will of course keep trying to force the OT into continuity with the PT though and further degrade the original's quality again and again. Boba and Shaw were only the beginning. It's all moot isn't it with GL constantly changing the movies.
