a couple of items that puzzled me

I've seen a fair bit of airbox modifying/eliminating go badly. Any time you modify any part of the intake tract be prepared to possibly have to re-tune.

Just enlarging the air inlet hole on the box is unlikely to change the tuning since it's also unlikely to change air flow, it'll make it a little louder which many people equate to more power. If you decide to open it up do some before & after speed runs to see if it helped or not. My guess is it won't just like you're guessing based on the logic that the hole is already bigger than the carb inlet, but it would be interesting to find out.
