I really like the idea of Ben taking the name of "Obi-Wan" when he becomes a Jedi Knight. I had a friend who did the same thing when she was confirmed in becoming a nun, and it adds additional monk-ish parallels to the Jedi of the Republic.
WheresBlackhawk, did you ever write out that EP3 treatment you talked about? If you did, I would love to read it - I have just finished mainlining this thread and I have to say that I thought your ideas were generally brilliant.
