As Ztalker said, its illegal to port files from one game to the other. Even if you own both and files from one game work with the second.
From our rules thread ( http://www.lucasforums.com/showthread.php?t=127725
14. Mods containing assets (models, textures, sounds, etc.) ported from another game are prohibited
It is against Lucasarts policy to port assets from one game to another. Holowan Laboratories does not condone porting of this nature, and moderators will close or delete any thread or posts discussing such mods. The exception to this is if the asset in question is present in both KOTOR and TSL. Also, modders may create from scratch mods that resemble assets from another game.
Not sure why your version of some of the tools dont work properly if oyu only have K2 installed. The seem to work fine for me withonly TSL installed. Have you tried asking the makers of the tools about it?
