Stop right where you are.

Put down the screwdriver and step away from the bass guitar.
I can't think of a worse thing you could do, than that, and I think you'd regret drilling holes in the bass after coming to your senses.
I get that it looks kind of expansive and empty, but that's the whole point. Even on regular Jazzes, I have never understood how people think that control plate looks good on the front of the bass, all on its own. I know Jaco immortalized the look, but I personally think it's terrible, since the SHAPE of the control plate is made specifically to mate with a pickguard. If it's designed to be out there on its own, it should have a different shape, IMHO.
I think that might be the most smileys I have ever used, but that's how strongly I am against your idea.
