I have no programming skills whatsoever but one thing I would like to happen or see as a mod is that after the Sanguine quest: A Night To Remember, if you pay for the ring instead of getting it back from moira, you can go back to Moira and actually consummate the marriage and be wed to her and she can do all the different things a normal wife can and maybe her wedding ring will be upgraded to the normal enchanted one, and maybe you can get some unique jargon from some of the guards like 'I heard the Dragonborn married a Hagraven, Love really must be blind.' and if you wanted to you could take her out on adventures and stuff but keep her marked as essential, I imagine she could be like a mix between Support and Magical Attacker, she can attack with magical spells and her claws or use her magics to heal and help the player.
