There are already materials that can accurately and with consistant repeatability change their form simply in response to pressure, and or centrifugal force. No requirement for flyweights or other external configuration triggers. Been awhile since I looked in to these and not sure about availability, but wouldn't these materials take care of this application?
Don't recall the manufacturer but was definately U.S. Perhaps been tried already..
