This is what i was thinking too.
In a vertical tank the bar could be a steel rod in a piece of
insulation, moved by magnets through the glass. Think windscreen

By the time the energy gets to the middle of the board it has dispersed. It would seem to me, that maybe what would work better is a bar that would move back and forth through the etchant right below the surface of the board. But that is just speculation, and I believe you would want to minimize the verticle movement of the agitating platform.
