This mod swaps the "npc/userdata/NIDXXX_faceMaterial.user.2" and "npc/userdata/NIDXXX_facialparam.user.2" files (which affect player-mesh based male NPC faces) with the ones from female NPCs.  

The files could be manually edited with MHR-Editor to make new faces but there are no descriptions for the values.
Others are welcome to try and modify the files to generate their own unique looking NPC.

Mod is update-proof as no prefabs are used.
