i think the phrase your looking for is ... "we're screwed !!"
the fronts are not too hard, take off the front hub extenders and fit the 5 bolt plates instead (of course this means 2 spares needed

but there are ways to do this using the space either infront of the fuel tank or the space on the driverside underneath, re-routing the exhaust, or adding a rear door carrier)
The backs are a little more tricky because the studs are in the hub inside the rear drums,, and the studs arent really long enough to do anything with. Best i can suggest (without having to re-drill both the hub and drums) is to look maybe at american pickups that run dual rears, or make adapter plates, and punch the studs out and thread the hub, then screw the adapters into the hubs through the drums. But here is the important bit, the adapter plates should be a strengthened type of steel not just regular mild steel and sufficiently thick enough to carry the replacement studs, if possible making the new studs inside the radius of the screws holding the plates, thus reducing the "peeling" effect that might be placed on the adapters.
in the event that the screws that hold the plates in place come loose the wheels should hold them in place
But your back to the same old problem, you still need to find wheels that will accomodate the hubs and offsets required, and the further out you stretch things width ways the greater the side loading you place on the bearings, it might be easier as you have on your stretch to just find 2 huge wheels to go on the back
