ebb and flow 4 4x8 tables one res

ok so i'm stumped at the moment. I know how to do a ebb and flow with one 4x8 thats pretty straight forward. But i'd like to do 4 tables at once and i need a huge res and i doubt i will find anything to fit under a table so they can all drain via gravity. So say i had a large res that sits in the corner, is there a way to get the overflow to go to the one res? Make sense? I guess i could have them drain to another res under the tables then have it pump back to the real res?

You may have to compromise and do 4 individual reservoirs, it'd take a pretty mean pump to pump 4 4x8s I'd think, and if you use 4, you may as well just do 4 reservoirs. I use a 115 gal table reservoir on 1 4x8 and 2 4x4s for flowering. Any way to make the overflow run to another res that sits in corner would just have to be lower level than tables is all, else gravity cannot do its work.
