Since it sounds like you're familiar with the field, any chance you've come across a CS- or C-mount lens with an autofocus motor? I've looked around a bunch and haven't had much luck. The current solution is a full C-mount-to-Canon-EF-mount adapter that has drive electronics in it, but it's eye-wateringly expensive and huge & heavy.
