Since the water tubes are aligned with the longitudinal axis it is
 possible we can find a core manufacturer to build one with the fins between
 the tubes orientated at an acute angle to reduce the drag.
 As per Chrissi's suggestion.

Years ago, Harvey Templeton built a formula ford with many advanced features.
One of those was a water radiator that was from a commercial fin tube
cabinet. It was about 2 feet by 5 feet and about 1" thick. He mounted it in line with
the lower control arms along the right side of the car. It was parallel with
the ground, no angle at all. It worked fine. Cooling about 55 HP.
