Terraformer block (changes nearby area into biome)

This block when placed would temporarily change the area(64 block radius?) around it into that chosen biome(with blending if possible), when the block is broken it reverts back to the biome it was before. This would be a late game block like a beacon, conduit or Lodestone. This block would address the problem of wanting different coulred grass or leaves for a build such as the bright green grass of a jungle without having to build specifically in a jungle or not being stuck with dull grass in a terraformed desert. It would also address the problem of wanting snow in a biome that doesn't have it or to prevent rain in another location.
