Bass are extremely aggressive, and can become territorial, especially in a confined space. I would say you would be playing russian roulette with your expensive cichlids. I think a species only or all native setup would be best.
I do not think your local DEM would raid your house if you kept a native tank, but you should check on the legality of it.
Most bass would outgrow any residential setup, but if you have a pond on private property you could always keep smaller fish and transfer them back. Just be careful not to introduce diseased fish into your pond in doing so. Also probably a good idea to acclimate fish when moving back and forth by using water from the same place the fish was caught to set up the tank, etc.
On the plus side bass are fun to watch, and are not shy about taking live prey in front of an audience once accustomed to their surroundings.
