I want to do it for my Taris mod at some point, since I really noticed it last time I was looking at it. I have plenty of other stuff on my plate though, so it won't be for a while. But I'll release it as a modder's resource when I do (as I mentioned above). Maybe you can contribute your anims?
Maybe it’s better to make a mod where, if you don’t meanly kill a target (set traps, kill prisoners), and if you fight them honestly - face to face, where they can also kill you, this will not lead to the dark side. In an honest fight, nothing happens - no points of darkness, no points of light. In this case, if I remember correctly, you will get a point of darkness only for the first, and you can honestly fight with the rest.
