Upgrade Whisperflow WFE -26 1.5 HP Motor to Variable Speed

I have a Whisperflow WFE-26 pump mounted where the side edge of the motor is just under the filter cannister.  I am considering upgrading my motor to the Century V-Green 1.65 HP VS motor and am concerned that the filter cannistor may interfere with the VS control door on top of the motor.  The Anthony Pools VA-52-2 filter cannister is approx. 1 inch above the top of the current motor and the side overlap appears to be approx. 1.5 inches (see photos)
