The way I understand it, if you keep the gear ratio constant and lower the wheel's CoF, you lower the friction load placed on the motor (when pushing) and therefore lower the current the motor draws. If you are limiting your speed to keep the pushing current at or around 40A, gearing that would bring a traction robot to 40A should only bring a mecanum robot to around 28A. That means that you can gear the robot to go faster (i.e. draw more current for the same load) by about 140% to bring the current back to around 40A.
