Rear mount radiator?

I am running into a build issue. I have mocked up my big block with a front mount procharger and I am running out of room for my radiator.
I can either run 2 small econo rail style radiators with the procharger intake in the middle or use my current radiator in the back with my CSI remote pump with a high level fill to my crossover pipes to the engine.
Any of yall tried to pull this off? was thinking about mounting it between my frame rails above my ladder bars and building a type of scoop above to help funnel air in above my driveshaft.
