I don't mean to hijack your post, but I am having a somewhat similar problem with this mod. Namely, I'd like my Daedric armor to use custom textures with glowing eyes. If I don't remove the Improved Closed Faced Helmets meshes then the helmet continues to be without eyes. But if I DO remove to meshes, then the helmet doesn't show up at all when I try to wear it. I made sure no other mod puts any meshes to that folder via the Data structure in MO. I've even tried to extract the vanilla Daedric meshes and placing them into the right folder, but still no luck.
