Does your design need 2 motors? We change direction for the lower roller by crossing a belt. Can also be done with gears.
Back to your original q., If you have the machining capabilities, I would make a sleeve for the pinion. I don't think globe pinions will be easy to find.
Off hand I don't know what material the pinions are, but if they are brass of steel, you could probably have the center holes brazed/welded closed, and re-drill.
The best solution really depends on the machining capabilities of your team.
