Do the Phantom Troupe even stand a chance?

Can the Phantom Troupe survive the whale ship journey? Other than Hisoka they're facing Kurapika (potentially) and the Heil-Ly. Not only that but their forces are divided and Bonolenov is already in danger of being killed by Hisoka.

Chrollo see's victory against Hisoka improbable, especially after Hisoka learnt his abilities. So he is plotting to steal an item from the ship that almost gurantee him his victory against Hisoka. But even without the item, Chrollo himself could defeat Hisoka. But he is playing into Hisokas hand as Hisoka probably has a plan and is already aware of some of the members. Hisoka might know what Chrollo is after, but Hisoka is probably planning to utilize Kurapika to defeat the other members of the troupe.

Considering how OP kurapika has become, not even Chrollo can defeat him. So unless they all team up on him, it would be practically impossible for them to kill Kurapika. But if they were to know about the condition of Emperor time they could drag the fight out in hopes of shortening his life span by using nen abilities. But even that seems difficult, they probably wont defeat Kurapika. But if Kurapika fought the 4th prince, then due to the fatigue from Emperor time they might be able to pull it off.

And if an all-out fight were to occur the Zodiacs would intervene. For the Troupe to survive they must kill Hisoka without notifying Kurapika nor the Zodiacs.
