Again, why?
Once you become traction limited, you're pretty much done torque wise. Every gear lower than that just decreases current draw. When you get higher, you get incrementally worse acceleration and greater current draw for incrementally more speed.
Maybe a better track to start on is what about a two speed transmission leaves you unsatisfied? Top speed too low? Not traction limited at the low speed? Want another gear for smoother acceleration?
