^ I agree. I think when you actually have the tank and visualize those fish in it you'll want to cut it down. I'd probably go something like this:
1x Silver aro
2x pbass
2x pikes
4x sevs
2x parrots
1x oscar
8x red hooks
1x SA lung
1x lima
1x fei feng
And maybe you could try the payara and 1 or 2 of the other cats. The aro, pbass, and to a certain extent the o's and pleco are just big bulky fish. I'm not saying your stocklist won't work because it could...but it would require a buttload of water changes or preferably a drip system, major filtration, and contingency plans for if/when somebody is on either end of a serious beating. Just to get an idea of what you're working with (and maybe you have already) try searching in the photo lounge for tank shots of 800+ gallon tanks and what's stocked in them, and compare it to your list.
