they have the tech to do it, so why not? i think could make anh a tad bit more complete by editing the duel between darth and ob1. they could keep all the alec guiness closeups and dialogue in it, but they could edit the wide angle shots and replace them with new better-choreographed ones. i suggest ewan(with old ob1 make-up and costume) performing this with hayden(darth costume. hayden's tall enough!) and having it inserted between cuts of the original footage. imo, that would be f**kin' nice! they have the tech to do it, so why not?
