OK, I whipped this up and it works pretty well except for one thing.
What I did was replace the wolf standing, dying, and decaying frames with the Joan the Maid/Scythian Wild Woman frames.
What happens with this mod is that when any wolf it is standing still, you see the wild woman, but when it moves and/or attacks, it switches to wolf form.
The only problem I have is that when I open the wolf decaying SLP in MPS, it doesn't have the "selected mask" with it. All I get is the "normal colors" and the "transparent mask" frames. Even when I import the wild womand decaying frames, the mask doesn't import. The end result is that when the wolf is killed, it turns into the wild woman dying, but then it disappears because there is no mask for the decaying frames. I have reinstalled AOK, TC & MPS, but it still happens. If someone wants to verify this, open SLP# GRA01637 in MPS. If you get the "selected mask," feel free to fix this mod so it will be included.
I was going to do this in reverse (wolf frames into wild woman) but when the wolf attacked, you hear the sword sounds, not the growling.
This is an open mod and I want no credit for anything! It wasn't my idea, and all I did was basically "cut and paste" some frames. Anyone who wants to improve on this is welcome to do so.
