Only issue I can see here in this configuration is with tensioning both idlers. If the motor is spinning in either direction, one idler is always going to be tightening the belt, and the other is going to try to be loosening due to driving forces acting on the idler from the belt and the smaller pinion gear acting on the larger gear.
How does one account for that, ensuring the belt stays in tension?
