This may or may not help, but figured it was worth mentioning. Atris, PFHC06, and PFHH01 share strikingly similar facial characteristics. Perhaps they are Echani and honor their mother, or more than likely one of the three was used as a base for the other two. That having been said I have taken the liberty of altering PFHC06's tga file to illustrate the similarities. Just drop the contents of the archive into your override directory, fire up KotOR II, and start a game using PFHC06. Now I admit while it is not Atris' head it is a viable substitute depending on the intended use. Feel free to use it if you wish, if not so be it.
