BackChest good inventory upgrade

I think it would be a good idea if we settled the inventory issue with not a backpack but a backchest it would be the same as a backpack but different and more like Minecraft a back chest would be able to have its own slot and would show on your back it would have upgrades too like an iron diamond gold and netherite upgrades each with different styles and there would also be things called implants like a smelting implant a crafting table implant an anvil implant and heck even a music disc implant so you can play music on the go but the iron tier would add a double chest of storage the rest would add more space for implants also there could be pickup implants and other quality of life implants but I don't think we should add implants that add storage cuz that wouldn't fit vanilla at all what do you guys think tell me in the comments
