Well then, after you've done that, why dont you then make a modern version of the same thing? same seed and everything but make it modern boats and instead of an imperial flagship have a cruise liner. And instead of a castle you could make a city.
Then sorta make like a jungle kingdom, with tree houses and stuff like that. You could even turn all the builds into one giant Adventure Map! Then you could have like a "smurf city" built in a mushroom biome with houses made of mushrooms (the big ones) and stuff like that?
There are endless possibilities, you just have to look hard enough.
