Mapgen like the Diggy map

[Why]

Hello Community,

I recently played a round on the Diggy Map. I like the way of the ore generation.
Is there any mod or an easy way to bring such an ore generation to a vanilla game?

I looked through the Diggy code and it's pretty complicated, maybe if you ask the devs at Redmew who created it for a normal map with Diggy resource spawning they could probably quickly throw it together.
