If Big Mom ends up fighting Kaido, I think it would be for the right to kill Luffy. After all, the reason Big Mom came to Wano in the first place was to seek revenge against Luffy. And since Luffy is within her grasp, I doubt Big Mom would let this opportunity slip away unless she would be satisfied with just taking Kaido's Road Poneglyph.
