If a Stone Ocean version is made, the main villain will be either Donatello Verses or Jongalli A.
Jongalli fits the bill of the main villain for the part 3 version (A Starter Villain that acted as a fake big bad tease) and Donatello fits the bill of the part 5 version (Someone that acts as a major villain close to the part's MV)
If a Stone Ocean version is made, the version of Made In Heaven will work based on a common fandom misconception- That it kills people
Perhaps due to accelerated aging?
Jolyne will be a Cute Monster Girl
Having a dolphin fin in reference to the "Jotaro's Wife" meme. Of course, this will go completely unexplained
