Tuning mod to completely disable werewolf face alterations?
I recently acquired The Sims 3: Supernatural, and I've been wanting to try using Werewolves. However, the werewolves always come with these facial slider changes that make them look goofy. While I know I could edit them in CAS to fix this, or copy the facial settings using a SavedSim file and s3pe's XML editor, this seems unsatisfactory as a repeatable, reliable, long-term solution.
I started looking through Supernatural's files to try and see if there's an XML that controls this. Unfortunately, I haven't had any luck.
Does anyone have any ideas on how to do this? Is this going to be one of those things that requires a more intensive mod like NRaas' stuff?
Thanks in advance.
EDIT: Okay, actually I looked and it seems to be worse than that: it completely blows away the Sim's standard slider configuration, rather than just applying a morph. Any ideas on how to fix this?
