This is a bit off-topic, so delete it if you want, but:
I'm setting up my next kotor playthrough, and want to try and prevent myself from making the game unbalanced through mods. To try and stop that happening, i'm using all the (decent) weapon models i can find to REPLACE ingame items, rather than adding new ones. I can do this, it's not hard, but i'm just checking if for example the Avenger could be used to replace a Repeating Blaster rather than a blaster rifle, what are the "rules" for this kind of thing? Can all one handed gun types interchange models? what about 2 handed guns, and swords?
