Your reasoning only holds true if you assume that there is no poor gearing, nor sloppy bearings, and a motor that is equally effective as a can motor. Only then you need e.g. 12Watts in any case. Therefore I said: " tackle the mechanics", because there lie endless possibilities of improvement. As an example, that R/C switcher I've shown:
originally used 150mA@12V at full slip.
After improving the axle bearings, and changing the drive train it uses 54mA@3V. Pulling power has even slightly increased due to the absence of motor-induced vibration.
