The XJ/TJ D-44 is a small tube -44, so you can in theory carefully cut the spring perches and control arm/track bar brackets off the -44 and weld them onto your d-35. If you make a jig linking all the pickup points and the pinion, it would make the transfer technically pretty easy. Lot of work though. Depending on the price at JYs around you, it might be easier to get a TJ D-35 from a junk yard that matches your front axle gearing and swap that in.
Regardless, when you finish, you have one more problem. The D-35 drive shaft is 1" longer then the -44 'shaft. It might work on the TJ long enough to sell it, but a pretty crappy thing to do,... If you buy a TJ axle, you can get the shaft with it. Not a problem for your rig, as the XJ shaft can be cut/shortened.
If you're not planning to go any higher then 3" lift, the LP front axle won't make much difference in the XJ. The HP axle might have a clearance issue in a TJ unless it's carrying some lift. Unfortunately, you can't swap the gears between axles, nor can you swap carriers and put the ARB into your XJ(unless you drop to 4:10 gears in your axle).
If you have a reasonable JY around you, it might be easier to buy an axle set from a TJ, swap them out on your buddy's rig, then do whatever mods you need/want to fit the -33/-44/arbs combo into your XJ.

My other car is also a Jeep,.. and so is the other one,.. and that one too. How many do you own before it's "a herd" ?
