You need Microsoft .NET to run Kotor Tool, so it would probably be too complicated for Linux to run.
Nah, [url=https://en.wikipedia.org/wiki/Mono_(software)]Mono[/url] has been around for more than a decade, and there are games that ship native binaries using Mono for Linux -- for example, Terraria, which is written in C# using XNA.
I just tested kotor tool under wine and it started up at least, and I managed to extract some bif file with it. I have no idea what else to do with it, but I'd say there's a fair chance it'll work just fine.
Also you don't really need any scripts to play the game. Just do a standard install under wine, and mod it if you like.
