Come to think of it, if both of them die in this fight, we'll never know how strong Hisoka/Chrollo is compare to Netero/Meruem. We only saw Netero fought Meruem and noone else. We know that Meruem is stronger than the 3 Royal Guards. But those Royal Guards only fought with weak shit fodders like Gon, Killua, Knuckle, Shoot... Morel is not really a fighter hunter.
Meanwhile, Hisoka also killed a lot of weak no name hunters so we don't know how really strong he is. Only things we can gauge is from the fight with Chrollo and the dodge ball match with Razor. Chrollo only fought the Zoldyck but it's not a serious fight. Razor lost to Ging but we don't know how strong Ging is compare to Netero (yet). Ging is the biggest mystery.
Can't make any connection without guessing. The only way this can work is one of them survives and fights one of the above hunters from CA arc.
