I don't like to say things like "it's impossible" nor I'm an expert, so just I will point you on the right direction according to what I see and believe. The problem with the non-circular-gears and the DLCJ is that they only share the same axis of rotation (are concentric) on one point, so when the joint turns (using the DLCJ) the variable ratio gears will crush each other or will separate, depending on the direction of rotation. So, the problem to solve (and I'm sure something can be done) is to assure there is a constant axis of rotation for the DLCJ. At this moment and with the circular design we know, that axis goes from distance 0 (surface of the DLCJ) to infinity, when the arms are at 180 deg. and then the lines parallel to the arms start to diverge. You have to think about it to find a solution. Keep on imagining!
