Nope. If you have two motors geared to the same gear, then there would be an odd number of gears between the motors - resulting in both motors spinning in the same direction.

I may not be the person who designed this, but the initial stages of a gearbox carry mostly speed and with little torque. As you increase the number of stages in a gearbox, more and more torque is transferred, and that is why the pitch of the gears decrease. The less teeth you have per inch, the larger the teeth get, and the more torque they can transfer.
This gearbox is going to have a lot of output power, as the two FP motors together are a little less than one-half horsepower, which is about the same as a CIM motor. (2 FP x 170 watts = 340 watts.) From this side picture, it looks like you have the auxiliary FP motor geared into the first stage from between the plastic ribs under the third stage. (The blue part is the original FP motor, and the red is the auxiliary FP motor.) Am I correct in this assumption?
