I'd reserve comment until I saw what the thing looked like.  In 
general, drilling holes is not a very effective way to reduce weight.
The strength reduction is often greater than the weight reduction.
One hole in the wrong place can do a lot of strength reduction.

Can you post a couple of photos on a web site?
