Aeronautic Structures

This is an idea that I think could have potential. The main gimmick of this idea would be structures generating in the sky, that are called Airships. These would look like a mixture between the End Ships, and a Shipwreck ship; but the key difference being the massive balloon that comes from the crow's nest mast. this balloon could be made of wool, and have an upside down egg shape to it. on these ships you would find loot, similar to what you'd find in a shipwreck, but you could also find things like a Spyglass, Amethyst Shards, and a new item, Rope Ladders. Before I go on about the Rope Ladder, I would like to say, that these Ships would generate in mountainous areas, and be roughly 15-30 blocks above the ground. Getting up to the Ship, there would be a Rope Ladder hanging over the side, that reaches to, or close to the ground. the Rope Ladder would work like a ladder mixed with scaffolding, but works in reverse. say you want to get down from a ledge, if you crouch out over the ledge and place a Rope Ladder on the side of a block, and continue placing, it will build the ladder downward. The crafting recipe for these could be 4 string and 3 sticks, string in each corner, and a line of sticks across the middle of the table. on these ships you could also find a variant of a villager, that is similar to the wandering trader, to whom I have dubbed the name The Aeronaut, he trades mostly things from caves, as he does not get to go down there. I hope you like this idea, Thanks!
