The tranny and brakes would obviously need to be upgraded, but the rest of what you listed would be unnecessary for a mall crawler. Anyone who wants to do serious wheeling would already be pondering the other upgrades. Dana 44s are probably stronger than what gets put in most vehicles that get mated with the hellcat. For my purposes, a 5.7l would be ideal.I would...but only if you upgrade like 9 other things so I don't die.
HD shafts, HD suspension, HD brakes, D60s, maybe HD D44s would work, trans and transfer case, because stock would last about 1/8 of a mile, the next 1/8th would be you skidding down the road sparking while your wheels and axle shafts fly out of the jeep.
So yeah Basically an Ultra 4 Wrangler lol, with no stock factory parts
700 HP in a Wrangler will probably not end well, I would love to see it though
