The impossible dream?

[Dirty looks]

In my quest to build the toughest, most capable, most luxurious '07 Yukon XL on the planet I have reached the next chapter.. Beefy Drivetain.
As some of you may know, there is no available locker for the front differential. My understanding is that the case isn't strong enough to take it.
And a 2500/3500 differential mounts completely different,but a locker is available
In 2012 to 2015 they changed the case to the same mounting style as the 1/2 tons. With the exception of an ear for a bushing that can be cut off. My understanding is that the mounting holes are just slightly further apart, but not so far that you can't get the bolts started and suck it up in to place thanks to the rubber bushings.
I know the CV's will be incompatible. They won't be anyways because I'm installing Dirt Kings 12" long travel kit. RCV will whip me up some custom shafts in exchange for a bushel basket full of money.
In the past I relentlessly prowled the internet for confirmation that this swap is possible but only found whispers of some guy that had actually done it.. no hard proof.
So, before I blaze another uncharted path on this project.. can anyone confirm that it's possible?
I am also swapping in the rear diff from a two wheel drive Escalade, 14 bolt semi floater.
Both will be geared 4.88 for 37" tires.
Thanks in advance for any light that can be shed on this subject.

Can you swap a 9.25" ifs front diffential in that year then?

I believe there's an ARB front locker for that diferential, no?

The 9.25 would be the 2500/3500 unit. The mounting style is completely incompatible..except, possibly the 2012 to 2015 models. But it's not identical from what I've gathered.
Supposedly will work but I don't want to tear it all apart to find out the hard way that it won't.
Manipulation and customization have already been standard procedure on this project. .. it's wearing me out.

The big stuff that's done so far. A thousand little things that don't make the list.

@randeez on this forum has done the 9.25" swap and documented it on his 2012 Yukon Denali on this forum.

Have you thought about a solid axle swap? TahoeOverlanding on YouTube makes the conversion parts.

The current generation pickups in the ZR2 variety have a front locker.

Wow, thanks! I will check that out.
A SAS doesn't meet the luxurious requirement. If I was building just a hard core trail rig I would go that route but I like to travel and won't trade off the sweet highway ride and handling.
A retro AT4 is vibe I'm going for. I've already re-badged it.

The wild part is how often people think it really is an AT4 and ask me where I got it.
I just tell them it was an early prototype, probably the only one in existence.
