Having built my main character around Necromancy I think what I would like most is some means of storing my dead thralls (read corpses). Before the patches you could keep a bunch of thralls in your basement and they wouldn't disappear every 5 mins. Lacking in any real means of facing off against the assorted hordes of Skyrim and having concentrated on enthralling Skyrims great and good, it was nice to be able to pick a thrall for any occasion.
My answer to my own slightly creepy problem - petrification. It would be great to be able to turn characters into stone and store them in my house. I always liked how Medusa had her collection of warriors in her den and I think it could be worked into the story as well. It would be kind of like Boba Fett and Han Solo - you could be sent on missions to capture errant criminals and debtors and as a bonus acquire a new power that allowed you to permanently store thralls in your house. Simply turn target into stone and then cart him / her back to your house. Whenever you wanted you could bring your victims back to life to fight alongside you and in the meantime you would have a mean collection of statues to decorate your home.
