I wouldn't bother. Just get your existing scoop mounted facing rearwords with a tiny bit of fibreglass work on it. Any bodykit place could do it.
The best area to have the hole in the bonnet to suck hot air out is near the front like on the rally cars. If you try to suck air out of the top mount u will find that that area of the bonnet is not as low pressure as the front.
The reason my coolant temps dropped so much is that instead of a scoop positively pressurising the engine bay and negating the air coming through teh front of the car. I went to a rear facing scoop which allowed air to flow out and created a low pressure area behind teh radiator and intercooler. Suck hot air out rather than blow air into the engine bay is the idea.
In fact, if you have enough air going through forward facing scoops u can cause the airflow through teh radiator and intercooler FMIC to go to almost nothing even at high speed.s
