thats what I would do. makes for a nicer install also as you can have the pumps in different areas with out them being tied togeather.

I would go for it.

the surface area really has nothing to do with the pressure of the water at the suction, it is all hight. that is my concern as most sumps are not that tall and we don't run them full so the suction head is going to be small. now if he had a 24" tall sump and ran it at 23" I would say most likely it would work, but that is unlikely.
