Personally, I don't think this type of game play would be appropriate for Skyrim. First, there are too many plot-dependent choices made by the player. These choices often cause complete opposite outcomes. For instance, Stormcloaks vs Legion. What if your friend chose to side with the Legion, while you became a Stormcloak? These types of vast player-chosen plot differences make co-op almost impossible. However, I could see a type of DLC, where players can temporarily leave Skyrim and adventure through a Daedra realm or something, where their choices don't effect the original game. That might be plausible.
