With God Valley happening soon, this is my guess for the fights.
Rocks vs Roger and Garp and maybe Rocks vs Harald
Whitebeard vs Garling

Silver Axe vs Gaban
Big Mom vs Saturn
Kaido either gets one shotted by Roger or he fights one of the Holy Knights
The other Rocks Pirates vs either the Holy Knights or the other Roger Pirates
