3 Rotor Idea well 2 and a half rotor

I got an idea for a better low end for our motors. Have a regular 2 rotor engine with another half size rotor in front off set to the side spinning the opposite direction geared to the main crank with the rotor spinning approximately 2000 rpm higher than the other 2 rotors as it would be a smaller rotor @ about half the size of the other rotors it could have a higher rpm with no problem. And at 2800 rpm @ idle it would get into the power band quicker and help out on the lower end and spin OK on the higher end without robbing power. I don't know if I'm explaining this to make sense but we need a Mazda engineer to think about this.

Lol, certainly creative

The thing is, Mazda went through alot of testing to find the rotor size that yielded the best power... Also, this would make the mechanics of the engine unnecessarily complicated, and make it seriously unbalanced.

Some form of forced induction would give you significantly more return on investment...

I was just thinking that too!
Wasn't there a 'History of the Rotary' video that showed engineers trying that same concept?
