This won't weaken the body at all but will make the air volume greater under the cone. Possibly this may give the electric guitar a "slight" acoustic advantage?

The second issue, I assume I'll have to drill a hole through the spider to allow the piezo wire to pass through?
When the piezo sits in the bridge recess I think the wire would have to be bent to an unacceptable level. A hole would allow a less strained cable on it's way to the control cavity.

I've actually just done this very thing with mine, for a similar reason. My concern was aberrant vibration of the wafer thin wood after i had modded things, so i have scored and gradually cut through to leave a void between the main body section and the rear ply top.

I have similar concerns about the Rod Piezo sitting funny. Not quite sure what to do about that just yet.
