Need help with vagina texture and collision in armor

[choco69]

I'm trying to make armors that have vagina collision and I can do this by overlaying the body that comes with the armor mesh with the femalebody.nif via BodySlide. The problem is that the mesh uses the armor texture files so the vagina has no texture. My question is: how do I blend a vagina texture into an armor's dds file. I tried using Calientes Texture Blender to on the armor's bbs files but despite growing 10 times in size, it didn't have any effects in game. There's probably more I could try with the blender but it would really speed things up if someone already knows what they're doing.
