There's no way my tire mod will be able to accommodate a WRX body, because the tires are just too large. It might work if you just overlapped the hard slicks and hard treads, but then you still wouldn't get enough clearance to run off-road. Also, for real off-road, you'd nee to seal up the front and back cavities where the axles are. If real dirt gets in there, you'll need to clean extensively after each run.
