Most A-pillars are hollow, made from stamped and folder sheet metal.
Could you use them to divert hot air from the underhood area to the roof?
Although you might need some electric blowers to pump the air to the roof, IMO the electric power wasted by the blowers will be overcompensated by the hot air effects on the roof boundary layer.

I think you could completely close the engine underbody allowing it to exit only from both behind the front wheels and to the roof.
