The problem is most head models are half-wrapped, in short they mirror themselves so if I put a scar on a head wrap (skin) it would go both ways and end up looking like an X. However there are some heads (like PMC01, or Azkul) that have a unique scar section that can be reskinned but I do not think there are any special heads that have the neck wrapped in that special way.
Another problem is that most female heads have already been used so unoless you want to go around looking like every other NPC you're more or less stuck. PCGM has some nice female head mods if you searched there but since we (not yet anyways) can't model new heads your stuck with the ones pre-made by the devs :(
Theoretically both of your requests are do-able but the odds of them happening are slim to none. If you'd like I can reskin the PMC01 head but it won't look exactly how you want it...
Edit: I found some links to new Female PC heads for K1 but not a lot:
