Some good ideas there but the one major snag I can see is the fact that Luke has had a son. Now I'm no fanboy of the EU and maybe in that side of things he's had son, I don't know? (Although I'm sure someone will enlighten at some point) but if Luke is to be a Jedi GrandMaster? surely he would've followed the old Jedi traditions of no attachments? The kid angle will surely be about Han & Leia's children. Again, everything is up for debate of course.
