End update idea

I have an idea for an End update. The End currently has very little progression after defeating the Ender Dragon, so I suggest adding a new End structure with a special item that can summon a new, extremely difficult boss. The boss would be able to fly, forcing players to use Elytra and making the fight require real flying and combat skill. It should also be difficult to cheese: blocks that touch the boss's hitbox (except bedrock) would be destroyed. Players would therefore need to summon it far away from their bases and properly prepare for the fight. The boss has a multiplication mechanic. After defeating it, the next generation multiplies by 2. The first generation gives 1 scrap, the second has 2 bosses giving 2 scraps each, the third has 4 bosses giving 2 scraps each, and the fourth has 8 bosses giving 1 scrap each. This gives 21 scraps total while making the final weaker bosses easier to defeat so the grinding isn't too frustrating. 21 scraps + 21 diamonds would create 21 new ingots. These can then be combined with Netherite to create a new armor tier stronger than Netherite. The Netherite combination also gives the armor its special ability: Absorption. The goal is for this to be an extremely expensive, difficult, true endgame progression system. Mojang can decide the exact boss design, balancing, recipes and implementation.
