new variants of spawners zones

many times you go down into a cave, you find the spawners but ... why not take advantage of the caves and cliffs to improve them These changes are to add more difficulty to the spawners, and make them have better decoration my ideas are: skeleton spawners: The skeletons being enemies that attack from a distance must have higher places, such as platforms supported by chains. These platforms would have fences to prevent players from approaching them easily, under these platforms there would be some blocks of bone that would make movement more complicated, also giving the exterior a slightly more varied shape, perhaps a kind of skull, and finally that the spawner is in the middle of the platforms. Spider spawner: Spiders are climbers, they could have high places which are covered by blocks to avoid being easily seen, something similar to basalt delta but at the top, the spawner hidden in one of those blocks. and finally the zombies: the zombies attack melee, just like the player, which makes it very easy to defeat them if you are well equipped, so for them it is more decorative, the zombies are similar to steve, so, the area is similar to a crack, so the zombies can push you and make you fall some blocks, or you can do the same. The spawners would be on top ... where the chests will be, I leave it to your discretion
