Not enough height, probably.
I took a look at my NSX to verify this. (In fact, right now I have the headlight units removed for an upcoming HID install, so it was even easier to see.) There is actually plenty of vertical distance there, to my amateur eye, so I think this is probably not the reason. However, the maximum vertical distance would come from placing the lights towards the rear of the current opening, and perhaps there is not enough room behind that point for the connectors and igniters and such.
