Biomes & Nature Mini-Biomes as Parts of a Town Built in a Specific Architectural Style

[Eitheriel]

Hi,
I had an idea that houses (or preferably entire towns) built in a specific architectural style could create their own mini-biome, where unique enemies with unique drop would spawn. What I mean by a specific architectural style is using certain blocks for building.
For example, a house/town made of Dynasty Wood could generate a Japanese-themed mini-biome with samurai and shinobi zombies and Sakura trees could grow from seeds.
Or a medieval castle biome built from Stone Bricks, where you'd be attacked by knights, swordsmen and crossbowmen zombies.

What do you think?
Thanks for reading.

Perhaps it would specifically have to be housing

But, not sure about this. That would require tons of new enemies so likely not
