I think this would be a simple mod but who knows.
Would it be possible to override (safely and removable) all heros to get a Revan Hero on all planets? I would just like anikins hooded model and animation, but reskinned to make it like Darth Revan in KOTOR. If its possible, remove the intro voice and add darth Mauls comment, "You worms are..." and for the hero music, play the final battle music, the Revan versus Malak battle. If all of this is possible then it would be a great hit.
