Anorne

I've been searching and searching for help but I can't find and answer to my question. How do I edit my companion's faces? Can I access the ones in Awakening as well? Any help or info would be truly appreciated.

I wanted to see if anyone could create(if possible) a assassin mask similar to this http://img102.imageshack.us/i/myassassinsb7.jpg/ and/or that with a hood combo
