As it happens, I've been thinking of adding feeder & feedee versions of the base sixteen personalities. It's been a popular request (including, I think, one of the very first comments after release!) that I've never fulfilled. They would potentially start that way, or it might be possible (though tricky, perhaps involving some special upgrades) to convert a 'Bratty' girl to a 'Bratty Feeder' girl.
I plan to introduce some of them in the 'More Personalities' update, with a poll beforehand to do the most popular combinations first.
