I'll let the beta people talk to you about beta communities...
What I was saying is with a planted tank the roots will go everywhere that they can and will eventually end up in any under gravel filter. If you were to do sand you would never have to gravel vac the tank because the waste will collect around the plants and be left at the top of the sand and easily pushed off it with a properly placed water current. This allows you the same options as before with less hassle.
The size from what you said if i understand it right would be less then 2 48x15x30 so around 140-180 gallons, a huge tank with limitless potential and if that's how big it is I would definitely use 2 fluval 304's if not a larger pair of canisters.
Best route in my opinion is put an intake at each side of your L and then put the spray bars on the inside spraying back towards the intake, or put intake as one end and spray bar at the other to create a continual current in one direction, good canisters wont have a problem going around your corner, this way you could have a high and low current and sweep all the debris into the planted area for a low maintenance tank or a low current and another spray bar at the corner to give an added push into plants
Edit- reread your idea - put spray bars on opposite ends pointing to planted center and have intakes around 18inches out of the exterior corner
