Question

I have very nice a Hampton Bay ceiling Fan which me and my wife love it. It has three different speed, LO, MED and HI. The LO speed has approximately 84 RPM and we will really love to be 8-12 RPM on LO speed. Is this possible or impossible? The numbers 8-12 RPM it dos not to be so perfect, just the idea for much more low speed. Thank you for your answer.
