so basically you have the 2 smaller tanks under your stand. Put a bulkhead (you'll have to consult elsewhere on height of the bulkhead, but I'd probably put them both about dead middle) in each tank and hook them to each other with flexible tubing (easier to work with, just keep in mind the reduction in flow)
I've got it displayed here how id do it, skimmer in the first sump then use the second as a fuge. you may have to tap a small hole in the cabinet from compartment to compartment to do this but I doubt a small hole would change its strength.
Yeah you can do this. I've done it before. I'd put the bulkheads near the bottom.
Keep in mind that because the effect of gravity on this system is going to be much less than that of a overflow, you need to create a very large pipe junction between the two tanks if you expect to get full flow through this. I'd use a 1.5" bulkhead to connect the two together.
