Making the End Requirements More Difficult

Defeating the Ender Dragon is easy, I was thinking that the recipe for the eyes of ender could be changed. Along with blaze powder from the Nether, ender pearls from trading, maybe nautilus shells to make the ocean exploration mandatory. Maybe wither flowers so you have to fight the wither, and sculk or something of that matter from the deep dark. How about something from raids? It makes the exploring of Minecraft more mandatory before you go to the End. Overall I think it would make Minecraft a lot more fun and it would increase the experience versus going through the motions.
