i think it would be fantastic to include the option of being able to tick off the daedric lords like so many of their former champions have. example being a necromancer after completing meridias daedric quest should make her angry with you and send out new potential champions out to kill you.

becoming boethias champion if you have already completed molag bal's quest (i think it was those two that are rivals? may have that wrong) would make molag bal send someone to capture you when you next sleep and you must fight your way out of the dungeon you are dragged into.

making azura's star the black star should make the shrine tender come after you, the list could go on and on. the main question here is how is there never a way to tick off the daedric lords? how could ways be implemented to make you able to do so?
