Yukon 4340 in 8.8

If keep the stock 8.8 C-clip shaft and add the ARB locker, can I later go to the Yukon shafts using the same locker and gears? I'd like to get some miles on the stock shafts as I save for the Yukon's. How involved is adding the non c-clip Yukons? I can't weld but can do normal wrench turning tasks.

Thanks
