If nothing else, Aspexia Rugatonn is impressed by the temerity with which Carissa Sevar proposes this!  The further details of her reaction feel hard for Carissa to model; Aspexia knows more about the strategic faceoff between Osirion and Cheliax than Carissa does, has hard-to-guess thoughts about tropes and what she thinks they say about an augmented Carissa facing off an augmented Keltham for control of Golarion while trying to seduce him.

She... plausibly... lets Carissa go to Dis and sell her soul first, and then demands details of the seduction plan from re-augmented Carissa before approving whatever Carissa really wants to do with Keltham, and gets sign-off from Abrogail.
