Shamelessly Copied....

Here's the ground board in raw form. Teflon pads and feet obviously go in the solid areas between the cut outs. The cut outs aren't perfectly round but the ground board is not a part usually seen.

The board weighed 6 pounds without the cut outs. The three cut outs decreased the weight by a smidgen over two pounds.

As long as the feet are centered on the Teflon, then it should be fine. I always worry about a lightened ground board though, they can become a spring board and cause the vibrations to be amplified. You will be able to tell that went it is mounted. Hopefully this will not be a problem. Looks nice though.
