The answers are:
Yes, it could be. The estimated cost would be around $7000
The reason is that the factory diff lock operates in conjunction with a number of other systems including ASC/TSC and is controlled through the ETACS-ECU.
That means lots of modifications to the GLX wiring loom, reprogramming of computers and, of course, the physical installation of the parts and their cost.
It just isn't worth it when you can get an aftermarket unit installed from a bit over $1K.
If you didn't want the diff lock to act exactly like the factory one (with interaction to ASC/TC) then it could be installed to work more like the ARB style, i.e.completely independent of other systems in the vehicle. That would lower the cost significantly, quite likely making installation of a second hand unit taken from a wreck a viable proposition. In terms of desirability this would position this alternative as possibly better than some of the aftermarket solutions, being cheaper and the diff having no significant reliability issues.

Not sure of the pressure required to activate but it is not much

Thanks that helps heaps mate, but are you referring to the centre casing or the housing? and are the axles bearings and brakes interchangeable?

The pressure is 0,24-0,39 bar.....the axles bearings are the same,but the shafts have different length.....if you want the oem locker,go to the wreckers and buy the all rear axle with compressor....

you need the whole diff housing, drum to drum as the centre pumpkin has castings where the air line and actuator moves. these castings aren't in the standard diff

You can run a line off the tank to a regulator to run the locker at 5psi and a 3 way air valve with electric solenoid for actuation. Also the left hand axle is about an inch shorter so you need one of these as well.
