Modding Question: Unique PC Heads

[IceQuinn]

Hello,

Say I’m using Human Female Head 6: firstly, how would I go about creating a new preset with it? Secondly, to replace regular Head 6 with a different one, any; from the many Nexus mods available, perhaps.

 

The goal is making the PC’s face unique, to avoid seeing so many NPC “doppelgangers” throughout the game. I’m very new at modding, and figured I’d ask.

 

Thanks in advance! ;)
