There definitely won't be that many fights, just because this arc just cannot be that long in the grand scheme of things. My guess is that this will follow the same format as WCI.
Luffy will fight Kizaru 1v1 in order to keep him away from the SHs, as the SH crew try to escape with Vegapunk, while Lucci and the fleet tail them.
Zoro and Sanji will get moments deflecting some big attack from the seraphim, Jinbe will get moments steering the ship out of danger. Maybe there will be a brief fight with the SH crew and CP0. However ultimately, I think Kizaru is the only one who will fall this arc.
