It's possible, but there are a lot of items in the game and they seem to be adding a lot of items without much use. Hard to figure out where you would get the materials, how much better should it be. I think swapping elytras and chestplates is already tedious, and they don't seem to want to add accessories or upgrades. netherite not that much stronger than diamond, and arguably not worth the effort, so that tells me they don't really want to add stronger armors and stuff. They want mobs to still slightly pose a threat even at full armor, weapons are pretty strong though. The rest of the progression doesn't really warrant stronger armor, and armor with extra functions would be tedious. I do think buffing netherite armor and especially the tools would be nice though.
