You might want to combine that with a default replacement skin and default replacement eyes and your townies and NPC's will be pretty as they can be.
I also use the teleport scrub and an object that allows me to alter their appearance (change appearance, facial surgery, change clothing) to fine tune their look. As a result my NPC's are no longer pariahs, as they used to be in my previous game. They are now fit to be interacted with, and even brought into the family.
Ha ha - I doubt JMP would do that in a thousand years.
If anything, I think Pescado would be more likely to do the contrary : make them uglier and more ornery. His fantasy land is not our fantasy land
