If you increase the number of character who are weaker than YC1 and YC2 it won't do anything.
The 2nd Admiral just rapes rest of the crew in a clean sweep like Warriors with Durant and goes to the 1st Admiral and they end Yonko.
He had Jozu and Marco last vs admirals until WB get heart attack .
Hell he made some of the weakness SH last vs BM , Oda can easily make up some BS depending on factors .
The luffy vs Kaido fight should be enough to show far Oda can bend the plot for things to happen lol .
