need help setting up my new tent

I'm getting a new grow tent, thinking about getting a 6.5' X 6.5' X 6.5' grow tent and i was wondering how many lights of what wattage i should use. Iwas thinking 2 1000 watt lights but I'm unsure how you would set them up because of the square shape of the tent.

I would get a 5x5 tent for flower and a 2x4 for veg. Fill the 2x4 with a 8 bulb 4' T5 and put a 1000w hps in the 5x5 with a cool tube with wings on ratchet hangers.

i can get a 6.5 X 6.5 tent for super cheap plus i should be able to yield more in a bigger tent, I'm just going to be using this tent for floweing, is 2 1000 watts too much for that area, i can use that much power no problem. i need room to move around in the tent to water buti want to use at least 2000 watts, should i be getting a bigger tent?
