I think trading in for another Navigator with the 2-speed transfer case, will be FAR easier than trying to do the driveline disconnect. The problem with relying on 2WD with the disconnect, is you can't ensure the front hubs are actually freewheeling when you flat tow, unlike the 2-speed T-case which has a flat-tow mode. If the front hubs spin the transfer case, it might not lubricate properly since the rear output gears are likely what slings the oil around.
FWIW - older F150s had a Neutral Tow Kit you would install to prevent the front hubs from engaging. You could probably add this to your rig if you are set on doing the driveline disconnect. But you won't may not have a matching knockout panel to install the switch into.
There are no Lincoln Navigators with "freewheeling" front hubs, so if that is your concern, then you might as well not worry about that.
