Trim tab linkage for a kick-up rudder blade

I am hauled out in St. Augustine, and one of the things I have to replace is the rudder blade. It's a 32-foot cutter ketch with a transom-hung rudder. It has a rudder blade that kicks up if the boat hits shallow water (as does the centerboard). I want to add a wind vane (a simple horizontal-pivot arrangement with push rod linkage to trim tab) controlling a trim tab on the rudder blade. The thing that has me stumped is how to set up the trum tab control linkage so that it can cope with the rudder blade kicking up. The pivot range on the trim tab has to be 20 degrees or so each way. Has anyone seen or heard of such a thing?
