Its basically confirmed that Zoro's target is kaido. If given the choice between fighting King and letting marco take king so that he can reach kaido, its pretty clear what his choice would be.
Anyway i am not saying it can't happen. I see small possibility that all the notable fighters can go at Kaidou together at some point during the battle. Bt that's about it.
Zoro fighting King makes most sense.
In all fairness the current situation( where are characters on plot) doesn't give Sanji good chances to face a calamity( I feel that only those 4 ahead + law have chances).
Oda can change it obviously but so far is grim the situation for Sanji fans when it comes to face Queen.

I dont know what to tell you if you really think Killer will even come close to outshining Sanji.
Oda is highlighting Captain-FM panels before the fights happens, they will go separate ways once fight starts. And this is again why Sanji is not with em, he is heading to same location through different path. And Law also is not there, and unlike Sanji, he will be fighting Kaidou.
