IF you've already made your character I'm not sure if there's any easy way to add the textures unless you were willing to remake your face. However this mod allows the raider races(Default, in case you aren't using FCO) to be used in character creation. Hopefully this helps!
I can't link because I have a recently created account, but the mod is called Playable Raider Races by crustytoeman. The ID for the mod is: 46411 (Go to the page of any mod on the nexus, replace the numbers at the end after /mods/ with that number)
