I made few changes to make the ancilliaries transferable from a character to an other keeping a certain logic ex. you can't transfer a mistress or an aunt. Transfering ancilliaries remain something optional.
The second change is to make pagan magicians (who're quite annoying) apear less often only in regions where your religion is under 50%.
To install it just put It in your mod data folder. It's compatible with any mods or savegame, this not make already gained ancilliary disapearn tough.
