It all depends on the type of plastic and where it is in the gearbox. You should work on the gearing calculations if you want to do custom gearing to make sure that the widths of gear can handle the stress. That being said, the best way to go about this is to redesign the gearbox to use off the shelf bevel gears. This would be much easier for cost, replacement parts, and time.
