Heres something to consider. Grainger has a Goodyear Polyurethane belt 115 teeth, 16mm wide 5mm pitch for $27. This would probably never wear out! Is there enough margin to handle the xtra tooth and width?
To simply answer this question....yes there is. It would only be worth it if it lasts longer than 2 standard HTD 570-5M belts. And that can be a pretty big if, if a pebble gets between the belt and cog. They just snap!
