I have no idea how Mihawk vs Zoro will happen.
Cross guild is a gag - they won't fight SHs for simple reason - Buggy is a gag and croc already lost to SHs.
I don't see Mihawk fighting with Zoro during SHs vs WG as well because Mihawk is no longer part of WG as warlord.
Mihawk joining RHPs doesn't make sense anymore as well because of Shamrock so we can safely deduce RHPs vs SHs won't happen.
So, best bet is
SHs and CGs will come across each other soon... around Laughtale or Lodestar..
Zoro vs Mihawk while the rest will be looking for RPG or fighting Navy

My theory is, Gaben, or someone else from roger pirates is the flame scar dude and will be in lode star with the 4th red stone.
Remember that Gaben told condom to come see him after elbaf stuff is done. Meaning he has something condom needs. So either Gaben is the flame scar or he will lead them to him.
But, CG will get there first. And Buggy will use his connection with the flame scar as fellow Roger pirates to either acquire the 4th stone, or to make the flame scar dude not give it to shp.
Buggy will then propose a davy back fight. The winner gets the 4th stone.
Buggy will aim to take Robin and the other 3 stone copies from shp through the davy back fights. Thats the only way he can gain any amount of progress for the op race.
So, we will prolly get lanji vs croc where its revealed that croc used to be a woman and lanji has some kind off identity crisis and embraces his okama side in the end to win, buggy vs condom in a clown-off that condom loses, and finally Zoro vs Mohawk to decide the fate of the shp and cg.
