You can definitely screw this up, and several teams have had failures using 9mm belts and 24T or smaller pulleys in the drivetrain. If you're not sure I really would go 15mm.
That this gearbox doesn't fit two 15mm pulleys is one of the reasons I haven't used it. It's a lot of space to ask for, true.
