I did three mods and put them here- http://www.wright.edu/~thompson.132/swkotor.htm
For the first one, I really didn't like the look of the blaster pistol or the heavy repeater. So I changed them! I assigned the disruptor and ion pistol the blaster pistol model and I gave the blaster pistol the heavy pistol model while giving the heavy pistol the ion pistol model. I gave the heavy repeater the ion rifle model and the blaster rifles the repeater model. The ion rifle got the disruptor model.
The second one is just increased damage. The game is balanced but i always like alittle more damage from all things. So all ranged weapons got 4x more damage(IE: Blaster Rifle 1-8 now 2-16) and the lightsabers got 2x the damage(because 4x on the lightsabers was just insane).
The third mod is just a combination of the two, I have mods waiting in the wings which i'll upload later.
Oh yah, props to Fred for the awesome tool. I started to work on a similiar one using a command line interface but I found yours and didn't need to.
