Heh Heh, yea the Camero --Z28, Dodge "Shaker hood", Plymouth "Bee's" all had various hoods, designed for racing, some reverse based on windshield "dead zone" at the base of the windshield!!
All the scoop's had to be over 1.5" above the hood surface, because of the air flow, "Boundry Layer"--
These were aerodynamic FAST cars-with various degrees of windshield flow angle, yet NONE of the scoops worked below 80 mph
Now take the Jeep (brick), put a reverse scoop on it, with a (brick) windshield !!
Better to just face it forward, you might feel a LITTLE difference in vent flow at your feet, maybe not
