Can the window motor be replaced with a banebots motor in the window motor's gearbox?

This would be a violation of R47.

Point of Clarification-Our question pertained to the utilization of a different gearbox with a banebots motor. Neither the gearbox nor the motor have been modified. Per Rule R47 which you cite and is posted below the integral mechanical and electrical system of the motor have not been modified in any way:
<R47> Motors and servos used on the ROBOT shall not be modified in any way, except as follows:
A. The mounting brackets and/or output shaft/interface of the motors may be modified to facilitate the physical connection of the motor to the ROBOT and actuated part.
B. The electrical input leads on the motors may be trimmed to length as necessary.
C. The locking pins on the window motors may be removed.

The intent of this rule is to maintain the maximum power level for each ROBOT, yet still allow teams to modify mounting tabs and the like, not to gain a weight reduction by potentially compromising the structural integrity of any motor. The integral mechanical and electrical system of the motor is not to be modified.

Again we have not modified any motor.

Additionally we have found the below listed thread which specifically addresses this same issue and you will note that the GDC response says “There are no explicit rules governing gearboxes. Provided they meet the rules in the manual, there is no restriction on how teams adjust motor outputs.”:

Since Banebot have a back order on gearboxes, can we use any COTS gearbox such as a gearbox from a drill with the motors we recieved from Banebot and Fisher Price?

There are no explicit rules governing gearboxes. Provided they meet the rules in the manual, there is no restriction on how teams adjust motor outputs.

Accordingly we would like a confirmation that we are indeed able to use the window’s gearbox with the banebots motor, understanding that neither have been modified.

Thank you

In the 2011 Kit of Parts Checklist, the window motors are listed by part number containing the motor and the gearbox. As such, this motor/gearbox is to be thought of as a single motor unit, and cannot be modified except as listed in Rule <R47>. The answer you quote involves other motors in the kit which are listed as individual motors and may be used with any gearbox.
