A Sky Structure

I don't think that this should be a dimension, or a biome, instead, I think a floating cloud, or something like that made of a cloud block, that could be a mix of powdered snow and honey, or slime blocks, would make a really amazing, unique, and rare sky structure. This could also have some sort of loot, and a boss. Maybe you could make take inspiration from Jack and the Beanstalk for the boss, giving the Giant a retexture and a use. The loot could be a large golden statue of something. I think that this is not only a new twist on an old idea, but it is also different enough from the Aether mod, that this may have a possibility of coming to the game.
