Has anyone tried this variation on Hempy Bucket?

Has anyone tried using 2 holes near the bottom of the bucket, instead of just one? So that the holes are diametrically opposed?

I know the purpose of the hole is to permit drainage of extra nutrient solution, but I've read that the hole also provides for the passage of oxygen.

Wouldn't two holes allow for more oxygen?

I was just wondering if anyone tried it with good results. Maybe if I made a Charlie Brown Halloween costume out of the bucket it would work even better?
