MacOS 12 on top of OSX 10.8

Hi everyone! I have mid 2012 MacBook Pro 13 Retina on which I ran OCLP with MacOS 15, but then I decided to reset it and clean installed OSX 10.8 through internet recovery.

I like that system a lot, I already made it usable and acquired some software for this old OS.

But now I'd want to run both OSX 10.8 and MacOS 12 using OCLP. Since OSX doesn't support APFS I wonder if I could try installing MacOS 12 over it using partitioning without losing any data that OSX has.

Thank y'all in advance
