make normal cave biomes correlate to the biome on the surface of the cave

I think the old caves are boring and just making them bigger is not enough so what we could do to make them even more interesting is to make normal cave biomes correlate to the biome on the surface of the cave this would be an especially cool change because of the new biomes generate next to biomes of similar climates thing that they just added some cave biomes that they could add for this change are ice caves (for colder biomes) sandy/terracotta caves (for warmer biomes) and more deep holes/ hard to navigate caves (for the mountains) of corse there would still be the normal caves every where but this would add a little more variation and more reasons to explore the new caves
