As Craterus said , the Huns are a good choise for a good and different game.

However , you shouldn't underestimate the difficult starting position they face, right nere the Vandals, if you decide to attack them , then those early battles are really important.
Especially since they have around the same tpye of stacks you have, and you need to make sure you keep a good army for the sacking of settlements , to manage your stacks.

All in all , I think you should find this a morale boosting experience .
