I've looked into this and it's not a difficult mod. The only issue with doing this on the 08+ is the ECU location. The ECU uses the stock battery box as a mounting point. If you move the battery then the ECU is kinda hanging out under the engine bay.
You would need to make some kind of custom mount for the ECU.
