Welcome to AquariumAdvice.com!!!
Good call on moving everything to the sump. I agree that keeping the all of the LR
is a very good idea. As mentioned, lighting this tank is going to be a bit more difficult, but with T5's you should be able to keep a good variety of corals, provided you have enough. the two triggers will pose a problem. Neither are considered reef safe. The niger has a better chance then the huma, but both should not be trusted with mobile inverts. You will be drastically limiting what you can put in your reef if you keep them. The damsels are reef safe but very agressive. Might not be a bad idea to trade them in as well.
