Change face texture without changing race

[Vlan]

Is it possible to change the face texture of the player without changing the race?

I am kinda curious because I like the idea of having a permanent scar after getting lobotomized in Point Lookout, but I don't like the fact that the Scar "item" takes up a place of a precious item slot (which I mostly use for other item pieces).

So the question is, does anyone know if NVSE or other script extenders have a function which are able to do something like that?

I know this is a few months old but what about adding the scar as a head part?
Like a beard or the eyepatch.
