Simple solution at least for mod classes. Since ROAR went with the norm and Novak/LRP rules for the sensored setups I don't see why they don't actually meet with Castle/Tekin on the Sensorless setups and get some simple rules for mod with these motors. It is mod so I can't imagine it would be too hard to iron that out. It could actually add lots of racers that might not bother to go to a ROAR event at least at local events.
Lets face it ROAR would of never went with Castle/Tekin for initial rules because Novak/LRP are in with ROAR alot more and then add most big factory guys race for LRP and Novak it was an easy choice.
