Did you ever get your controller or are you still using this system manually? I plan to build a set of plates similar to your smaller ones and I am starting a fully automated system design and build to run it. I've already got the code and a crude UI to control the actuators as well as control speed of the boat. My boat did not come with Perfect Pass, so I started by building my own and it has morphed into something similar to Auto Wake.
I just started a thread over on Wake Garage if you are interested in taking a look.
