This is a techo question mainly for Eham and Aerisan.
In TES3 NIFs you could specify multiple UVs, so you could map diffuse, normals, heightmaps, etc, differently.
I'm wondering if the same could be done for Skyrim models?

Just so there is an official answer to this post. I have already spoken to happychappy. But multiple UV sets in Skyrim are not possible as the number of UV sets is determined by a single bit, basically it has UV's or it does not.
