Each of the overflow boxes has two holes drilled in the bottom of the tank. I've been reading about the Bean Animal system and if I could pull that off it would be perfect. But that system uses three standpipes in the same overflow box. I have thought about putting the the third emergency drain in the second overflow and using the fourth hole for the return from my sump.
This would basically mean that I've got one functioning overflow. The threads I've read have made it sound like you can run as much flow as you want through the one main drain. Only in an emergency would that second overflow drain be used. It would mean that the first two pipes have become clogged somehow rendering the first overflow useless.
I'm not trying to create any massive water movement in my display with the return. Just trying to get the water down to the sump for skimming/heating/dosing, etc and then back up again.
Am I wrong in my assumptions with the overflow setup?
If anyone has any other suggestions, I'm open to hearing them.

No, you are not wrong. As of yet, I have heard of one "confirmed" use of a bean system in dual overflows, and it was done backwards—it was not working.
Honestly, I don't think dual overflows is the place for a bean system, or a hacked in herbie either; I may be wrong as I was using siphon systems before herbie published. The best bet is don't buy reef ready tanks anymore, (overflows and holes are usually too small) or pull the overflows and start from scratch.
