A system for conflicting enchantments

A much more expensive anvil that has the ability to add enchants that would normally be conflicting, such as infinity with mending. Currently, endgame players can quite easily get maxed gear, so it would be a great challenge for endgame players to make perfect gear without the restrictions of conflicting enchantments. As for the recipe, it could be the same as the regular anvil except the iron ingots are replaced with obsidian or netherite ingots, and the iron blocks with netherite blocks. Also, if this were to make it into the game, the Too Expensive! would have to be moved higher, or removed entirely.
