I wasn't saying that you specifically should do it, just that Salk's request would make more sense if it harvested the heads and plonked them on the standard bodies. Someone else could do surgery. Left as-is they would be compatible with your textures with no further effort, but if you allow 3rd party mod reuse then they could probably stand to be remapped.
You shouldn't be encouraging the use of Workshop mods. And no, loose textures aren't any more compatible with Workshop mods than other mods.
Mac and Linux users can use the multi-platform HoloPatcher as a drop-in replacement for TSLPatcher, if it is required.
