Swap to a non-Toyota axle? I'm running the factory axle and even still use the original 4-cylinder third member housings. It's good enough. The Toyota 8" axle is roughly the same as a Dana 44 in strength or IOW, a standard duty 1/2 ton axle. The upgrade path is a Dana 60 from your stock axles and that opens a big can of customization, particularly in the front.
I don't see the need for a 23 spline case for most people. Even with a doubler it's not generally your weak point. If you break a 21 spline gear you are probably beating the living snot out of your truck and quite likely towing it to find the /really/ hard trails.
The best future proofing you can do is change all the fluids, add gas, put on a set 30x9.50 BFG ATs and just drive it. I guarantee you that doing trips with guys from Rising Sun spotting you will be pretty amazed at what your little stocker will get through. The only other thing I would add sooner rather than later might be sliders.
Sounds like I have no compelling reason to switch away from my stock rear axle then. If I were going to go crazy on a build, I'd probably take a welding class, buy a welder, and make some insane custom tube buggy/crawler/monstrosity. Or get out and walk

It's good to hear that the 21 spline setup is good enough.
I need to go look at what tires I have on the truck again... I think they're all terrain mud and snow tires that are about 30 inches? They still have enough tread for at least a season of playing around.
Sliders look like a good idea. Yet another addition that I'll need a friend with a welder for.
