Floating Islands in Over World

With Aether around the corner, I’m not sure how possible this suggestion is anymore, or necessary, but thought I’d bring it back from Discord anyways just in case.

——

Idea A. This was a suggestion made before the first blighted biome came out, I thought floating islands with little research domes containing the blight around the Open World would be nice. Just a little bit of the plant life enough for those who don't want to explore the Blight biomes to collect from safely. I included the only blighted biome we have now (this was also made before learning the cactus explodes, so maybe not include them? or do for small % danger haha), but thought could do this with either all the blighted biomes scattered around open world (if they all come with collectable blocks/plants), or just the one that might appear in the Aether.

Idea B.

Contains creatures and plant life that lives on the floating islands.

b1. Flying Fish (need better name) design based off of baby lionfish. They are see through glass like, colorful floating fish that hang around water or puff flowers.

b2. Puff flowers are dandelions like flowers that give off little snow like particles or the falling nectar particles.

b3. Cloud Swan (I got nothing, just thought it be cute. with particles coming off them, and more birds)

b4. A overworld ghast (placeholder name I call them tots). They are smaller than a squid, spawn from water and float in the air. They are none-hostile unless hit where they'd attack with bubbles. b4 is based off a mob concept I made up awhile back, but it's actual mechanics are either not possible or op, but I'll include it anyways.

"Drop: 0-2 Tot Tears

Using the tear, you could make a potion that'll only work if turned into a splash potion.

Once it's a splash potion, you'd throw it in natural water source and within a 4x4 area it'll rain for a short time( the splashing water particles when it rains just appears on top of the water not actual raining from the sky, or the dolphin particle on top of the water). This will make it better for fishing (alot better vs a normal rain storm.) enchanted rods would just make things more lucky with loot. And adding glowstone dust to the potion would make it a 6x6 area. " Like said, too op, was a idea from 2013

Note: this overworld ghast was suggested way before the baby happy ghast was announced, so it’s concept might not work anymore, unless it could be an Aether variant

With the Aether coming out, no clue if we are still going to get an End, but i’ll still include this old concept like I did with the rest.

Idea C. Would have a custom End portal on it (once the end is added), Normally the end portal would need many eyes of ender to open the portal (I showed 3, but could vary). The portals would come in different styles as well as the default on the ground one. They'd spawn around Open World, like ruined nether portals but on floating islands. (Unless the end is going to be deepdark related or opens at spawn this idea is void, but thought I'd include still)

So these are the 3 ideas I came up with giving different reasons to add floating islands/in the air structures around overworld.

As for below them, could just include small pits, like the islands floated up from the ground with glow lichen in the pits to prevent mob spawn in the dark.

Or, little camp structures below left behind by archaeologists that would have investigated the floating islands with a lantern as a light source.

Another option, glowing plant life below, from seeds that could have fallen from the islands. If the floating islands aren’t from the overworld but traveled from somewhere else.
