A really cool fanfiction could be where Luna and Celestia swap roles for a day. This would lead to all kinds of chaos and hilarity in Equestria as they try to adjust to each other's responsibilities. Ponies would be very confused by the sudden change in the day - night cycle.

Princess Celestia can raise the sun, has strong magic for ruling and protecting Equestria. Princess Luna can raise the moon and also has magic related to the night, like controlling the stars.
