This radiator is divided so that the top outlet allows the water to travel to the passenger side of the car then flow back to the drivers side. So the tank on the drivers side a divider in the middle. So to the radiator doesn't care where the water starts as long as it goes through all of the tubes. I would think the problem would be plumbing the bottom hose ALL the way from the passengers side UP to the drivers side. Also air will get trapped inside with all the bends and twists you will have to make.
I think you need to keep looking.
