if you can pull that off i would definitely play that mod!!!
sounds great!! but maybe add some more info in the mod on how the exile found revan.. or visa versa..
Maybe HK-47 would be a more suitable droid to hold the crystal for revan since revan did custom make him...
Is carth going to be part in this mod as well? and how about dustil? Maybe dustil can join your party? and why not make it for TSL? you have some more options there, not?
those are just some of my idea's/suggestions
all by all, it sounds like a great mod!!!!
