Simple Changes to mob spawners

We know our mob spawners that have been with us since like 1.3 or 1.4 something along those lines... i think we should have it a lot more complex instead of a 5x5 or 6x6 with a 1x1x3 gap there should be a lot more complex deals with it... potentially not complex that would ruin the vibe but we need new structural organization. Potentially new structural architecture for all different "NATURAL" mob spawners.

1. ZOMBIES

There should be an extra deal with it instead of 1 room. Potentially some sort of ways to hide chickens a chicken cage? With a lot more hight variants some corner bits and bobs... and a potential trap..?

2. SKELETONS

Should also have the corner bits and bobs.. but the loot is way way way more unique loot tables... and the skeleton spawners should be way rarer than any other spawners.. and it could have chains dangling from the sealing or lying skeletons if you could get those in the game too :>

3. SPIDERS/CAVE SPIDERS

There should be a kind of net shape... the mob spawner area should be in the open.. Imagine walking down a cave you spot a cobweb think it's a mineshaft and what a surprise a spider net with a spawner hidden in-between the cobwebs and the other surprise it doesn't end there you can see diamonds through the other side... it shouldn't contain loot but making that gives caves a bit more of a nice and alive feeling.

4. BLAZES (in the nether of course...)

It should also be in the open (of course not in a wide open cave..) you could a giant room with lanterns dangling off.. chains as mentioned with the skeletons thing pools of lava... and a throne where the blaze spawner would sit of course don't change much with the block pallet except adding in magma blocks which could hold fire in the corners... and red nether brick to give the texture/color a bit more of a variant.
