The reason FCA went with auto, torque management. That's the only way to make the dana 44 hold it. You go to manual trans, no TM or hydro coupling ( torque converter. ) Bye Bye 44's.
I have the older 5.7 with auto in my TJ. I did go 60 in the rear. You can feel the Hemi give up the power at shift points ( T.M.) Newer stuff has much better timing, so you do not feel as much trim.
So, if you are going to 450-500 foot pound of torque.......... Dana 60's plus 1350 or bigger u-joints. Or keep it on the street.
This is why I put a 60 in the rear, I saw enough rear blown ring and pinions on bigger than 37 inch tires on MT Jeeps that I knew better than to roll the dice. The front i kept and it’s been fine I don’t go crazy when I’m wheeling I crawl it

My 2001 Anniversary edition had a Dana 44 for the rear axle and it was a 5-speed manual transmission. It was built over 22 years ago, but it the Dana 44 with a manual. Obviously it was the 4.0 straight 6 and not a 6.4 Hemi...

It’s already being done, but you do you man. Why do you care?
Some people feel the need to shoot down legit ideas/ questions/ discussions of others to make themselves feel better and justify their own choices.

also: lack of reading comprehension, would be my guess as this was addressed in my initial post

Or that people will figure out how to do anything if they put their mind to it.
