Before we worry about what types of commercial blades should be allowed I think its worth you trying the normal circular saw blades at our Fleet event. As we are aware that you and only you are running them (if anyone plans to please let us know) then we can work around employing extra measure's when using your robot to use as a test scenario. It may be that the blades fine, or that the blades breaks but all the tips stay attatched. Atleast then we can put together a proposal to allow all forms of commercial discs excluding angle grinding discs.
