The only issue is that you'll need to gear the differential so you can never overspeed the motor. If you ever find yourself approaching 90 on a long downhill, you'll need to gear the differential for that, as the ADC doesn't take kindly to overspeeding. Consequently, the taller the gear, the less acceleration you'll have. (Again, maybe not an issue with the 9".)
If there's some kind of overrunning clutch you could put between the ADC and the diff, you could use a much lower gear ratio for better acceleration and efficiency, and still not overspeed the ADC when the truck exceeds its top speed. I don't know if there's an option that would work for that. (Or, like you said, use the transfer case just to the front wheels and put it in neutral.)
