EQ's are already part of the personality profile. You have different EQs for Home and Car right now as it is. Adding new tuner-module IDs will simply extend that past just "Home" and "Car" to "Home", "Car ID 0", "Car ID 1", etc. I don't know if beeps are part of the personality profile or not.
You probably won't get a custom playlist for each person. But I could see the currently selected Wendy Filter being remembered with each personality profile. That would be interesting.
