I haven't seen it done yet, but I think your best performance dollar ratio solution is to buy a wrecked tesla and use the rear drive unit in place of the transfer case.
The left output becomes the front driveshaft output and vice versa.
Jack Bauer on these forums has a solution to drive the Tesla unit, and EVTV is developing as well, and they are not the only ones.
The Tesla is a single speed 9.73 ratio, you will need to upgrade the stock open differential, RVTV has a nice solution.
You can play around with ratios here.
Have fun!
