I want to make a new model for Darth Nihilus, but I want to know if making said model is possible

Hello.   As of right now,  just to let you know, I have a really old computer, and so I won't be attempting to do KOTOR modding until I get a new computer.  With that being said, once I get a new computer and start doing KOTOR modding, I am planning on doing a pretty ambitious project for KOTOR II.  So, we all know what Darth Nihilus's model looks like in KOTOR II right?  Well, my goal for this mod is to make a new model for Darth Nihilus that is based off of more of the concept art and fanart of Darth Nihilus online, where he has loose wraith-like silk robes instead of the more bulky, leather robes seen in the game.  Reference pictures here....

So yeah, kind of an ambitious project, however, I would like to know if making a model like this even works for the game's engine and animation, and if I could make loose, wraith silk-like robes that can move smoothly in the game's animation and engine.  If I can't do this, what do you suggest would be the closest way to make a model that looks very similar to this?  If this is possible in the game, what do you recommend I do when creating this model?  Could I make it in Blender and port it to KOTOR II?  Or is there another way?  Any help would be appreciated, thanks.
