In this I added more upgrades. Meaning you can use chains and leather armor to get chainmail armor. Chainmail and iron for iron armor and so on.

leather-chainmail (using chains) -iron (using iron ingots) - diamond (using diamond) then to original netherite.

wood pickaxe - stone pickaxe (using cobble) - iron pickaxe (using iron ingots) - diamond (using diamond) then to netherite.



leather helmet - creeper head (using gunpowder)

leather helmet - zombie head (using rotten flesh)



leather helmet - skeleton skull (using bone)



leather helmet - turtle helmet (using scute)

I didn't do gold because most gold items aren't useful (sorry if you wanted gold)
