I am trying to follow some of your logic but get lost in the terms.
Light is electromagnetic and sound is pressure.
The solution, as I see it, is to phase lock the two vibrations. If they were touching, the vibration would reach the Moon at the speed of light. Let's call this Longitudinal vibration. If one of the same billiard balls were tossed into a lake, it would create a 3d wave in the water. Let's call this Transverse Vibration.
