Dan,
The way I read the specs, +/-60 degrees is the max travel from the center position. The spec sheet for travel distance/time is for 40 degrees from center to either side. It is pretty easy to couple a 2:1 gearing to give you the extra travel, external to the servo or even a double linkage depending on what your eventual need might be. Trying to fool the servo is not going to work. When you feed a PWM value to the servo it uses the internal pot and electronics to move it to a defined position (within the accuracy of the servo). The internal pot is the sensor that tells the electronics where the output shaft is.
