Just a few warnings, LOL. It is possible that you may run into aggression issues with a Domino Damsel, but it might work out okay since you have such a large tank.
Also, I have heard possible reports of Pistol Shrimp killing Cleaners.
However, I have also heard success stories keeping them together, my guess is that it just depends on the species.
What about some kind of Tang? They are great, very active and colorful, and your tank is big enough for a lot of choices.
