Not sure what you meant by improving overall flow, as the ZN6 oil pan opening would also serve as a outlet for air to flow out of the engine bay.

On creating a cover - probably not worth the work at this point (and you could just get a used GR86 panel anyway).
It's not exactly a direct fit, you need to get the GR86's front sway bar mounting brackets and it's OEM front chassis bracing ~ $120 for all that.

You could be right about the oil pan opening venting heat, but in my amateur opinion it seems like the opening is far too big to create a pressure differential that will allow effective air evacuation, especially compared with the "louvered" flaps you have created. I'm just thinking that if that area was covered, your louvers would siphon out heat even more than they already are. Could be completely wrong about that though. Would only require some sheet metal and 3 screws for testing though!
