I am ALL for Oblivion adventures as side quests.
Ideally I would like some function of the equivalent of THe Mages Guild or Daedric cults that allows you to open or access a few lasting gates to Oblivion's various realms, at least some of them, most prefferably ones we have not seen like Meridia's, Sanguine's and Cold Harbour (though I doubt the last will be allowed for ratings reasons, unfortunately), that would allow the sort of back and forth access which Sheogorath's gate to The Shivering Isles provided.
Since Morrowind has been devestated, perhaps Dyvath Fyr himself has moved into the mountains of Skyrim and brought his secret Oblivion opening lore with him.
