There's no problem using 9mm pulleys in the drive, given you do the math, and take a look at what worked in the past. 971 ran 9mm, 24 (or so) GT2 pulleys with 3.5" diameter, 2" wide wheels and a traction limited low gear. As far as I know, they never had any issues ratcheting. There are plenty of other threads discussing this, but the horsepower ratings Gates gives are conservative for FRC applications.
