Congrats Michelle, you stole my idea.
I've been wanting to do a damsel tank for a while as well, and even had the same "mbuna" theory.
I was going to try it with some of the "less-aggressive damsels" (is there such a thing?) - sergeant majors, chromis/blue reef chromis, and possibly some of the smaller yellow-tails.
But you could also go with the really aggressive ones and see what happens- mixing humbugs (nasty boogers), blue devils, and dominos.
Either way, I would think live rock and a wet/dry for biological filtration, in the hands of an experienced aquarist like yourself, could be a manageable way to go for something like this.
Meanwhile, i will anxiously await pics, so I can vicariously live through you without lifting a finger.
