I like your ideas for Fett in Jedi, but I think it's a major case of easier said than done, y'know? Ady is a wizard, but...I dunno. It might just turn out to be the most interesting change to Jedi of all. If he even changes that scene at all, that is! Haha.
And hey, now there's a question: do you consider the Holiday Special canon, Ady? :p
