I tried something similar, minus the gearing. With the model finished in OpenSCAD, the STL exported, and being sliced, I started thinking about the conical bearings. The problem is that the part of the cone with a larger radius fights the part with a smaller radius and generates friction. Since Emmit's design is hardly friction-free, your design may actually be an improvement, but mine wouldn't have been.
