Your scoop is not my cup of tea based solely on its visual appearance and proportion; however, I like the functionality and the workmanship and I applaud you for both.
I think you are absolutely right in wanting to reduce underhood temps, but having said that, the real problem with the JRSC BBK is in fact the high intake air temperatures created by the blower itself and it's effect on timing retardation; and cooling the outside of the blower won't cure that problem.
The solution to the problem is to ensure the air coming into and through the snorkel and filter is as cool as possible to begin with, and then cooling it at the source of the problem which is inside the blower case.
To do that I wrapped the SVT headers, I insulated the entire intake plumbing tract, and I installed a water meth injection system. Not only does it lower the IAT significantly right at the point of entry into the cylinders, it also seriously increases the effective octane rating (even with 87 in the tank) - both of which can allow you to tune for quite a bit more power.
I may yet install a vent in the hood, but that's more for the hood's sake after a long run at the track. With the setup mentioned above, I was able to maintain full power throughout a 30 minute run at basically full throttle and top speeds approaching 200 kph. I don't think a hood scoop could have done that, and even worse, I think it would add drag.
Just my .02
