[Jeff Waegelin]

Just to add the official wording from this year's rulebook:

<R62> The motors in the kit may not be modified except as follows:
• It is acceptable to modify the mounting brackets and/or other structural parts of the motors (output
shaft, housing, etc.) as long as the electrical system is not modified and the integral mechanical
system of the moving parts (bearings, bushings, worm gear output stages, etc.) is not changed or
removed.
• The gearboxes for the Fisher-Price, Drill, and Globe motors are not considered “integral” and may
be separated from the motors. FIRST will not provide replacement for parts that fail due to
modification.
• Caution advised regarding the ½” drill motors: You should not replace the blue wires, however, you
may shorten them such that there is a minimum of 1.5 inches still attached to the motor and solder
heavier gauge wire to their cut ends. Do not attempt to unsolder the blue wires from the brush
housings. The plastic brush support housing will distort if exposed to soldering temperatures and
the alignment of the brushes will be affected, which can permanently degrade motor performance.

Your idea would be considered a modification not included in the list of legal modifications, so it would not be allowed. I suppose it's something you could do for learning purposes in the offseason, but you wouldn't be able to use it on next year's robot.
