Spore blossom spreading caves

The spore blossom could combine itself with the moss in the lush caves to spread the caves. If the spores from the blossoms had a chance to have a bonemeal like effect, this could activate the moss and assimilate surrounding caves, spreading the lush cave. For this to work, the spore blossom would need to be able to be placed on all sides of surfaces not just the bottom, and to have a chance to be created by moss block bonemeal. This could have an interesting effect on surrounding biomes, for example a dripstone cave could be turned lush, making the deadly stalactites/stalagmites harder to see. It would also make it easier to find these beautiful caves, and could make it so going back into a cave that has been explored before could be an option to get these lush plants.
