HL2 citizen face/animations with my texture

Hi there,
Is there a way to attach my skin (http://www.filedropper.com/group01) to the half life 2 citizen (group01) models?
The original models were just for ragdolls & NPCs but I’d like to use them for player models.
If someone could help me I’d be really grateful.

I’m thinking you could probably hex the skin then decompile the hexed citizen models. Then, simply recompile them with player animations.
