Great forest hills biome

Great forest hills would be a rare, large biome that could only be found in the overworld. these forests would have simmilar terrain gen to alpha and beta. cave riddled corners, huge overhangs and bridges of land, floating islands, and wacky, extreme mountain generatoin. and i dont mean the new caves and cliffs mountains either. i mean amplified mountains that are absoulutey MASSIVE. These mountains [which would obviously be spread out from eachother] could reach the new height  limit at max.

just a cool biome, that's it for this suggestion.
