I think the biggest challenge lies at the front. The diff needs to be removed from the sump and remounting where the steering rack lives to make any sense of the driveshaft alignment to the front wheels. the drive shafts are then in the way of the front springs/shocks. Really the whole front of the car would need re engineering. Not impossible but a lot of work. Dax did it on the 4x4 rush
