Not with a versa planetary
I haven't done a 2:1 ratio before, so I'm not sure about the optimal way to do it. One way I can think of would be to drive a 16 tooth sprocket/belt off the motor and run a chain/belt to a 32 tooth sprocket/pulley on the intake wheels.
You could also just run the 775pro at 3:1 in a versa, which would still be faster and more powerful than mini CIMs at 1:1
