you still need a way to get the distance sensor data into ML (possible via USB for example, but there may be other ways)"

Lidar contacting directly to lens motors via USB connection using ML, that maybe would work with STM lens (with loop focus ring).
One thing to think about is the resolution you can get using the two approaches.
That is driving the lens from inside, ie using the ML or Canon code vs rotating the lens externally via an add on device.
Just a thought.
