Hideous

So, I've been looking all over the internet for the last 3 days, trying to figure this out, but I honestly have no idea. IArmorTextureProvider will let me create armor with a new texture, but what I really want is to render a 3d model on a part of the player, say, his head. Is there any way of accomplishing this "easily"? IItemRenderer does pretty much what I want, but I don't think it works for when you actually equip armor, no? Any ideas?
