I know there is "exorcised" elite package, but it is different from "illuminated" ones where they drive out daemons themselves through strong will. Also, I read somewhere that there even existed such women who bind daemons to herself and then consume it (Slaneesh was not amused as his several greater daemons were consumed if I remember correctly).
How "Illuminati" elite package would look like? I think it is unexplored area.
