So, despite all the other stuff in the thread what coral would you like to keep? It will be tricky with the amount of waste those fish make and lights bright enough to keep coral coupled with several of those fish will eat any invert = a ton of algae. Carbon dosing will help with GFO, but with lights strong enough for coral I would be worried about algae unless you stick to low light softies as those will do well with elevated nutrients too. I had a tuskfish and it was invert annihilation!
I have linked this before but here was my tank before I got sick and it became too much work. Even with all the automation it was a lot of work and stress. But it did get featured by AI and won an acro growing contest on reef2reef

You can see that I had a large bioload, especially for a stony coral reef, but not a lot of large biomass fish.
I don't think really and one of those large fish is a problem (except the naso tang - they are so active, the others are not so much), but all together that is a whole lot of waste and big fish. The red sea 650 is only 64" long which I think is a problem with the naso. I doubt anyone has tried that exact combo of fish, and personality does come into play, but I wouldn't be shocked if eventually there was a death from other fish.
