This would be an awesome arc if it were to happen. As for the family situation, when it comes to death (excluding Kalluto) the only family member I could see dying is Illumi which most likely is going to be Killua's last obstacle before the series ends. Even with all the massive upgrades that Killua's achieved up till now, it still doesn't compare to the amount of experience that his father and grandfathers have.

As for Kurapika, even though he is no match against 5 pro assassins(being Illumi, Silva, Zeno, the great grandpa and Maha), you still gotta keep in mind that we don't know what the chain on his index finger can do. It's most likely his ace in the hole.

I'm pretty sure if this situation happened, it'd only involve the 4 protagonist and possibly Alluka and the Troupe. Other than that, I don't see the H.A. or anyone else getting involved in this. The arc would probably end with Killua reasoning with his family. I get a hunch that Togashi made Kalluto and put him in the Troupe for a situation like this.
