I am in the same boat. About 2K in mods (namely better tires and LED headlights). I can climb some pretty serious hills as it is.$31.2k to buy (plus tax and title), plus ~$2k for the soft top, $1k for the rails, and another $300 for interior stuff like phone mount, interior organizers, grab handles, and entry guards leaves me around $34.5k which is still less than the sticker price of $37,200.
Seeing some of your mod lists and costs is insane to me, even for very enthusiastic hobbyists. Makes track work and mods for performance cars look cheap. For $80k I'd rather be in a Land Rover.
For the most part, the majority of mods offer little return for a couple of reasons. First, almost noone wants your exact setup, so they are not willing to pay anything close to what you paid. The more important reason is if you put that many off-road mods into a Jeep, you likely beat the snot out of it.
