This does sound cool but it will not be like a 4WD system where you can disengage front hubs. You'd still be pushing around (rotating) the entire powerless front half of the xDrive system, it would only be disconnected at the front driveshaft out of the transfer case. I'm not sure all that metal is meant to be whipped around that way for very long. Imagine all the twisting forces going on inside the front axles and diff that are normally damped out with power application from the TC.
