You do know D44 and D30 share the same u-joint size, knuckles, ball joints etc.
D50 D44 and D30 all share the same yoke spline count.
And everything will still be 30 spline if I remember correct.
So upgrading a D30 for something just a tinny bit bigger is not worth it in my opinion.
If you are trying to stay in Class1 for RCrocs that is a different story, but you cannot upgrade to a D44 anyways you are stuck at a D30 (stock front axle).
The JK44 is a little larger yoke spline, and I believe the u-joint got a little larger too, and the ring gear is almost the same as a D50.
You can shove D50 (HP) or JK44 (LP) gears in a stock D44 housing with some work. Doesn't fix the u-joint problem. Then you can weld on D50/D60 Cs and Knuckles for larger u-joints.
A lot of work where a D60 you already get all that.
D60 you get both a larger Yoke, Larger Gear, Larger U-joints, Larger Axle shafts, for no extra cost.
Now you can buy RCV shafts and get the same strength as a stock D60 but for $1200 I'm sure you can get a D60 to fit.
D60 can still be upgraded quite a bit. but stock form will do you alright for 35s. I would upgrade the D60 outer 30spline shafts to 35 chromo, I broke a bunch of D60 30 spline outers with 35" tires and tired 4cyl.
As for the size the tube D60 is way beefier so you don't need a truss. If you want to spend a little time shaving a D60 you will only loose about an 1/2" of ground clearance over a stock D44 housing in that one spot.
I checked Car-part.com there are a bunch of D60 in the $500 range.
The only reason you have to upgrade your rear axle is if you want the same bolt pattern. Does your rear 8.8 also have 5on5.5 bolt pattern? You can probably find adapters. There are a lot of options for the rear axles and they are supper simple to swap, especially since it is leaf springs. The widths don't need to match narrow rear is common.
It is easier to stay 8 lug but they sell 5 and 6 lug all on 5.5 or larger front hubs for the D60.
Now fitting a D60 into an XJ can be a little more of a challenge but people do it.
Also shortening a D60 is easy, and new custom length shafts is only a phone call away.
Not as intimidating as you might think.
I would rather drag my diff on everything than be broke.
If you have any questions about building the axle let me know.
