Say, would it be possible to put Revan into the game at all? I'm not sure about being able to adjust what weapons and force powers they use, but wouldn't it be easy enough to add or reskin a character and even put in Revan's voice for the game?
There is already a mod which places the KotOR Era in the game. (Hero stuff, the Republic, the Sith, etc.)
Take a look at here:

It also adds a game mode with the picture of a stormtrooper's helmet, which is the battle between heroes. Pick the KotOR Era and choose Evil. You should have Revan, Sion, Tray, Nihilus, and others.
