I was walking doing a quest today when I thought of something. Would it be a good idea to have a place in the game specifically for people to fight bosses they already defeated and can only be defeated once? Like for example, named dragon priests, Alduin, various quest bosses such as Gauldur etc....I'm sure it'd be fun to have a rematch with some of them (especially Morokei ).

I was thinking about maybe having them reappear once a day/week/some specific time so that we don't just have a good memory of these fights, but can also relieve them, try out different tactics/difficulties etc....

What are your opinions?

Could have something along the lines of the Final Fantasy 10 monster arena, where you'd rematch the bosses, but slightly altered appearance, and alot harder.
