Copper and Tuff Golems Bosses in the Trial Chambers

The trial chambers have several challenges but they don't have a boss, what if there were two new rooms in the trial chambers? One room would be for fighting the Copper Golem Boss and another for fighting the Tuff Golem Boss. Both rooms would be closed and the only way to enter the rooms was to craft a special key for each room. The Copper Golem Boss room would be opened with the copper key which would be crafted with 8 trial keys and a block of copper and the Tuff Golem Boss room would be opened with the tuff key which would be crafted with 8 trial keys and a block of tuff. The Copper Golem Boss can drop copper and an item that is used to create the Copper Golem that lost Mob Vote and some special item with some power (for example, creating lightning when you right-click on the ground or on a mob when if you have the item in your hand), and the Tuff Golem Boss can drop tuff and an item that is used to create the Tuff Golem that lost the Mob Vote and some special item with some power (for example, giving a haste effect until the durability ends or until you deactivate the effect by right-clicking with the item in your hand). Each Golem Boss could have a different fight from normal minecraft fights, for example the Copper Golem Boss could have phases in which each one, the Copper Golem Boss would be more oxidized, one of the phases he could shoot lightning at the player and the Tuff Golem Boss could break and place blocks at the player's feet.
