It does not matter where you put the overdrive on the transfer case. Rear output flange, brake output flange, front output flange, unless the overdrive is placed ahead of the transfer case (input shaft), it will only effect that one output, and the corresponding driveshaft where it is mounted. This means that you cannot use the overdrive multiplication while the transfer case is ingaged into four-wheel-drive.
Having said that, and now having reread your post, I believe I misunderstood your question. If your are asking if there will be a change in driveshaft speeds between the front and rear outputs because of simply relocating the rear driveshaft to the brake output flange (but not using an overdrive), then my answer is no. The transfer case shifts into low range at a sliding dog clutch on the internal shaft between the input and brake output flanges. This causes all three output flanges to turn the same speed, all the time, whether in low or high range. The front output is shifted in and out of gear at the lower shaft located between the front and rear output flanges.
Hope this clears things up and that I didn't cause confusion by misreading your question.
