Sure, post a link. I think ive seens ome mods called "order 66" but they just make the coruscant jedi temple map like that. I was think more along the lines of it being a mode, where you can choose it on the menu like assault or hunt, with varied jedi of the good side and different heros for each map.
Different maps could have different looking jedi and have a different hero.
For instance, on Felucia, you could have several jedi in cool looking camofloge (definately did spell that right) instead of in the regular robes.
