Motorized Gakken STRANDBEEST desktop model kit Answered

Has anyone replaced (or plan to replace) the Gakken desktop strandbeest model kit's wind turbine with a toy DC motor and gear system?  If so, I would love to hear what specific motor and gear system was used and how you mounted everything on the model. It would take a motor with adequate torque to operate the twelve legs, a properly sized gear/gears to operate the model at a moderate speed  and some simple way to connect the motor/gear to the existing gear system.  I've seen hacks for K'nex, tinker toy, erector set, aduino, & custom builds but nothing added to the Gakken mini strandbeest kit except a hamster wheel.
