Lower Deepslate chunks

If there's one thing I would change about the deepslate, it would be to make them spawn at lower Y levels in some areas. Why? It has to do with the new caves and how they generate. You see, most of the time I find a new cave, 95% of the time it's all made of deepslate, and I rarely find new caves made out of normal stone. How this would work would be that in some large areas of chunks that generate deepslate lower than -1, so some bigger caves can be made more out of regular stones. There's nothing wrong with deepstate, but I just want to see a swiss cheese cave made out of stone for once.
