It might be a little difficult with software, since the torque applied to each wheel is different. You could try scaling the back wheels down by 4.67/12.75, by simply multiplying the motor output by that ratio. Small signals to the motors will most likely have a strange affect on them as well; it's kind of a strange situation. Just make sure you have the right transmissions ready to swap in for your first regional.
