Possibly unrelated, but neat if it is a reference, in Japanese folklore, where we see a man in the moon, they see a rabbit. So Luna having a hare patronus seems very appropriate.

American Indians in the South west also see the rabbit in the moon. A mad hare patronus fits Luna on soooo many levels.
