The sole purpose of Mihawk joining Cross Guild and Buggy then pushing towards the PK race is for Zoro eventually facing off with him. So far, Buggy's luck was tremendous, fate pushed him to become a Shichibukai and now even a Yonko, who is carried by Mihawk's power, who has double to bounty of Crocodile and a bounty even surpassing the perceived captain.
Buggy's previous luck suggests that he will outlive his competitors one way or another. That's the entire narrative around Buggy. He definitely won't fight the RHP, and he won't face of with the BB pirates either. It will probably start with BBP vs RHP and then continue with SHP vs. BB, either before or after the WG. While Buggy, as always, will somehow wriggle his way through and probably end up in Raftel.
Buggy going down any time earlier doesn't fit the narrative of him making it through by some means.
