I believe we can design a hybrid between the DLCJ and the non circular gears, infact, it would be a DLCJ with variable ratio, allowing us to eliminate the bearings and at the same time working like the Annirak drive. Probably something like this:

Red line represents a spring and blue line represents fishing line that can be shortened to turn the joint.

Funny, but it looks more like the original Annirak drive now. I hope this can work. Less bearings sounds good to me.
