Remember that torque x speed=transmitted power. On a cvt disk,( or even with gears or sprockets) the smaller the diameter, the greater the force required for a given torque. In other words if you make it small, it needs to spin really fast, or have really high contact force (or both). Even if the materials could withstand the contact forces, heat buildup due to inefficiency of non-point contact could be an issue and would be more troublesome as you go smaller as there is less surface area to dissipate the heat.
