Straw Hats handling 100 ships fleet with 2 Top Tiers would be too fucking cartoonish.
Gotta remember there's the BBP there too and the seraphims initially aren't on the marines side either until Saturn comes makes it to each of them indidually
Lucci and Kaku are def on their side too, it's too late for them they already teamed up.
Techs from Vegapunk too, and Bonney.
Remember these are now one od the strongest pirate crews which is why they sent 100 ships in the first place with government ship among them.
Slight possibility the grand fleet makes an appearance too but not a guarantee still.
