Thread lade on the Meow ID speculation, but I actually think Faust would be a good fit.
Big tits aside, there aren't a lot of opportunities for Faust to show emotion in an ID. N-Corp's canned experiences making her like Kromer is why the Gripper ID is the way she is.
The musicians are the same, they were presumably functional, well-adjusted people, until the Pianist's song made them go insane.
