Sure, we could do that, but it would a) cost more money and b) take up about an additional inch of robot width.

Looking at the rated torques, I think it extremely unlikely that we'll ratchet or break a belt with our setup (especially given that the torque ratings Gates gives are for extended use, and are somewhat lower than the effective maximum torque for the short service times they see in an FRC robot). 449 used 9mm belts on 36t pulleys without incident last year.
