Wonderful idea!
I have some random thoughts about AI:
What about party AI improvements? It's even hard to roam with them because they try to get stuck all the time. Party members seem to be not bad with offensive force powers and strikes (well, it could be better, I suppose), but they also need to learn how to use those individual buffs like force speed/force immunity and etc (activation out of combat, perhaps?). Manual activation of all these buffs in 3-jedi party is frustrating, considering their duration. At least force speed buff AI activation is a need. And HK-47 never uses his power shot (is it fixable?).
I would like to see jedi guardians (enemies and Juhani) jumping back and forth (they should use their advantageous force jump). Also enemies' combat strikes should be based on their weapons - sneak attackers should be stabbing in the back with flurry all the time, tanks and low-damage opponents should go with power strike, guys with 20-20 crits and high damage should go also with flurry and etc. If an enemy has several strike feats, he should use appropriate - probably enemy check his attack vs defense of party members (not to waste power strikes on high-defense guys, and flurry strikes on toughness-guys). And of course, enemies/party members should not constantly cast debilitating force powers on already debilitated enemies - sometimes it's better to do some damage.
Anyway, I don't know if all these changes are possible to implement. Still a great work - AI is ridiculous sometimes and definitely should be reworked.
