I'd ask the creators of the USM to re-release their mod to make use of the TSLpatcher, to ensure maximum compatibility with all recent releases. I, for one, volunteer, if they take the mantle up, to make bump maps / specular masks from their "diffuse" textures for the mod. and if they could add to the package a better lightsaber glow and even more colours I'd be in heaven.
I also ask the community: would you actually want it?
