Not a lot of "you gotta do anything in the AvA."
Other than adding a battleship, you can do what you want in custom arenas. There is a small all sea terrain called avasea. Load it up and set up the fleets where you want with the aircraft that you want.
Advertise it heavily when you are going to run it.
If you consistently run out of room and need more than a 16 player capacity, we'll talk.
