I looked through the "Art of Episode III. Revenge of the Sith" book the other day. In it, it talk about how they originally planned for Han Solo to be raised by Chewbacca on Kaayyakk (sp?). The sidebar was accompanied by drawings of a young Han in brown, leathery outfit of tunic, shorts, leggings,and boots.
Just think about that. It would have been 3 for 3:
!) In Episode I: We learn that Anikin Skywalker--the future Darth Vader---built C-3P0.
2) In Episode II: We learned that Boba Fett was a clone of his father Jango Fett.
3) and now in Episode III....
It was very possible for Lucas to do this. But for whatever reason, he didn't.
Let's breathe a collective sigh of relief.
