gears for porro prisms?

Hi. For my big binocular project I'm going to have porro prisms next in line before the eyepiece holders, and have wondered whether anyone has heard of using interlocked gear teeth, or other mechanisms, for coordinating their rotation for adjusting interpupillary distance. I don't want to get too complicated, but don't want the ep holders to rotate freely relative to each other either. Thanks.
