Mod compatibillity for Cubic Chunks?

There is a mod called Cubic Chunks which changes the shape of chunks and allows the world to generate downwards for millions of blocks without bedrock.

I want to make a mod which adds new ore/stone gen in those new areas below Y level 0, however vanilla ore gen will not work.

When generating CC ores I need to place the ores during cube population, not chunk population, however I do not know how to do this.

I can also make a few edits to the code if needed to customise things in a way which Mcreator cannot normally do, however I don't know much about coding in Java so although I'm willing to attempt complicated code edits I won't be able to just make new custom Java elements from scratch, I'll need something to copy/edit

Could someone help me by suggesting a way to do this? If not with ore gen then perhaps using entities or structures to generate the ores?
