1, Fred's Kotor_tool can do it in a semi roundabout way now. If you have both his tool and tpc2tga installed in the same place, you can convert any file in the texpacks with a couple clicks.
2.. He's working currently on first, the rest of the format problems for some of the images (like portraits) and also, integrating the code to be native to kotor_tool, so as not to have to extract, then shell out to the other exe to convert.
He's been hard at work, so I wouldn't think it'd be long till we see the next improved version.
