If this is possible I could save myself a lot of money!
Actually, it would be a completely FWD car. The center differential allows the front and rear axles to rotate at different rates. An open differential simply lets them spin at different rates, but does not provide any power transfer. An open center diff = FWD.

You could probably hack the car to FWD by removing the rear drive shaft and sealing the coupler. I think someone on the first or second gen forums did this mod.
