Outer Limits 4x4 Board

Hi guis,

Does anyone somewhere tried to put a rear diff locker (original Nissan) into the front axle?
I mean, by changing the satelites for the 31 splines?
..and cutting the diff housing to allow the actuator...
As I have to put my 5.1 gears I think that I'll try to do that...

Any ideas, please?

if the side gears are physically the same size so that they can be swapped, it should work??
