What do you even want to see from GF2's story at this point?
I'm honestly starting to think making a sequel with SKK as the main character was such an insanely limiting choice. It should have been a new protag and new dolls so we didn't end up with the same person fighting the same exact villains again. And at the end of it SKK will either be dead or starting GRF so the end state can't be a surprise as is.
