It weighs 8,000 lbs and rolls on 35” tires. I don’t feel the need to do anything further to the brakes, certainly not rear disk that is for sure. The only rear disks I would ever entertain would be a complete late model GM or Dodge HD truck rear axle swap. Those are both disk and drum. Huge disk and calipers for service brakes and a drum and shoes inside the disk hub for the park brake. That is the only way to have rear disks.
I also run 13 x 3.5" drums on the back of my Suburban but it is on vacuum brakes. Even with the Burb being considerably lighter than the K10 it doesn't stop nearly as well as the much heavier K10 with hydroboost.

i wouldnt even swap to those axles. i used a dodge 80 in my truck and specifically looked for the drum variant. the caliper hat parking brake is a pile donkey scat. they hold... ish. they are notorious for getting really crummy and being a pile of crap. and mechanically a drum is a better system. IMO the advantage is that the disk set up wont collect dirt. that is the only reason i ran it on my jeep.
