More importantly than do you want one; I ask, if we got one would you like something "in world" or "out world"?
This means would you want something that fits the universe of Skyrim or something like Dead Space's Dragon Age 2 cross over, being "out world"; something that fits in terms of looks but is inspired by something out of the Skyrim universe. We recall Fable 2's Halo suit for instance:

That said, what kind of ideas could you see for each?
EDIT: I'm looking for items to clarify, maps and real world trinkets are great but this topic is meant more for armor or weapons...something wearable or useable in the game.
