-Add some sort of config option to change blocks of structures based on biomes. A thought is to use a tag list of blocks (that users can add) with a separate json config file that users can specify what tag list of blocks to use in a specific biome for a structure. Definitely will be a TON of work to do.

uhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

many new structures such as outposts and villages use nbt files which can be overridden by datapacks so that's the best way to change a structure's blocks

chose nbt as the direction. Folks can change not just blocks but the entire structure by datapacks
