Nether Pyramide

Following the last snapshot (20w06a) and the new Netherite stuff I had an idea that can be implemented in Minecraft: The Nether Pyramide.
Because the Netherite stuff resist to lava when dropped in it I thought that it would be a good idea to give interest to the player to take a lava bath by adding a new structure (the pyramide) that will appear in the lava lake in the Nether.
Inside you will find 8 ancient debris as a treasure (giving interest for the player to go in without making it too OP) but also a mob that will try to make you fall into the lava! It could be a simple skeleton that will shoot you from the outside of the pyramide or a new mob: The Sarcoflage. This new mob will be a Nether-like Shulker that will throw fireball to you (not the ghast one but more like an arrow shot by a Flame enchanted bow) that will set you on fire and knock you backward (except if you have Netherite stuff indeed) also if you get touched by those projectile it will automatically close your Elytra (like that if you try to fly in the pyramide you will have to be carefull not to get shot)
By adding those you will add a new structure to the Nether, give more interest to go swimming in lava, add a new challenge into the game (imagine trying to fly around the pyramid without getting shot) and all of that without breaking the game
