Thanks a bunch for the schematic. I was going to use the same control for the LE slats as for the flaps as well as controllling the LE of the horizontal stab. The electrical is relatively easy; it's the bloody mechanics of smooth operation of the airfoils. I have to solve the flaperon issue for the A-6 since it extends the length of the flaps and also (as flaperons do) operates in only one direction.
