Qui-Gon needs to be at the end of ROTJ. I know, I know, everyone's pissed enough as it is with Hayden being there (which is totally understandable it doesn't make sense for his ghost to be younger.) but Qui-Gon is one of the few Prequel characters that actually resonates with the audience like the OT characters do, AND his role is important considering he's the one who started the whole force-ghost craze, and plucked little Anikan from obscurity.

That's as far as I would go in terms of integrating Mr. Jinn into the OT.

I've had this thought as well, but I'm not entirely positive I agree, though I think we should discuss it more, and maybe we can make it worthwhile. I completely agree that he was one of the most interesting PT characters; he had substance, was well-acted, and made the audience believe the Jedi were actually mystical and cool. I especially agree with the tie-in with the force ghost thing and as I said in my first post, he needs to communicate with Obi-Wan. My concern is that Luke has absolutely no contact with him, and he would simply wonder who this extra guy standing there is. To me, if there were some clever way for Luke to get to know him even briefly, then I would be with you 100%.
