It doesn't seem like your bronze texture is based on the biggest texture, so I probably would try do something with it myself instead, hopefully getting a better result (not to say your modification isn't good). People with medium or low texture detail would still get the high detail bronze ligthsaber, but I doubt just 1 is going to murder their PC's .
EDIT: Just noticed that your custom texture has no "transparant background"... meaning it would appear with a black border ingame. Which would be bad. I don't have the means to make transparent .tga files, so if we decide to make a custom model I probably need VP to brew something up...
EDIT2: Or maybe my editing program is just really crappy at opening, since it doesn't want to properly load up the original files as transparent either. So... did you save it with a transparent background?
Could give some insight how you changed the models to use the modified color? I'm not really the modeller of the team, so I have no clue myself. I do noticed the sabers all have the same icon, but there's not much point changing that (if I even knew how too 0_o).
