Random wild and maybe ineffective idea...

Since cooling is always an issue as we add boost, etc. Please tell me, would it improve cooling airflow if there were some vents toward the back of the hood, in the hood?
Is it functionally better for all the air to go through the radiators and then down under the car, or would this idea functionally be an improvement, cooling wise?

The further you go to the windshield the higher the pressure, and this is actually not what you want imho, a so you don’t want to create a positive pressure in the engine bay.
You want more cooling, so more air flowing thru the radiators. This higher flow of air can be achieved by increasing the frontal pressure, and create under pressure after the radiators. You can do this for instance with aerodynamic aerodynamic changes like a front splitter. Or more simpler, control your engine fans, to turn more often and faster.

This was just a completely uneducated random idea by me. I have no previous understanding of the fluid dynamics of engine compartments and radiator air flows.
I'm not sure what you mean by "creating under pressure" after the radiator. I'm assuming you are meaning a relative difference between the pressures of in front and behind the radiators, which we want to be as high as possible...am I correct?
Are you saying the ideal situation is for the air to come through the radiators and then hit the front of the engine and then go down and out and that this allows for the highest differential of pressures relative to the front and back of the radiators, thereby increasing the "sucking" of the air through the radiators?
How would we control the fans to come on sooner? Are there uprated fans that would drop in?
