Someone needs to make so that you can use an instrument and sing upon joining the Bards College. Also an idea to think about is a Writers Guild where one is given a blank book to write in. You could write anything in it, a short story, a novel, an epic, a poem, just plain nonsense. You then submit it to the guild which then spreads it all across Skyrim. You'd even get random remarks from the guards or people saying how good or bad it was.
I realize this would be no easy task to implement but what do you think?
