What if the younger generation Jojo's fought the main villains that their parents fought and vice versa?

1. Jonathan (or Dio) vs.Diavolo

2. Joseph(young) vs. Kira

3. Jotaro vs.Pucci (White Snake) I know that they fought already but no C-Moon or Stairway to Heaven

4. Josuke vs. The pillarmen (Individually)

5. Giorno (no requiem) vs. Dio (Part1)

6. Jolyne vs. Dio(Part 3)

I know you could argue  that stands are stronger than ripple users but you gotta remember these are the JOESTARS( in their prime) were talking about here! They can overcome just about anything.PLUS  I'll give Jonathan and Joseph the ability to see the stands (to make it fair).
