I think Kurapika HAS to be the main character for the Succession War because it’s almost 100% connected to him. Tserriednich is a major player and he has the remaining Kurta eyes, Kurapika is the bodyguard of Prince Woble and the biggest thing... The Phantom Troupe are on the ship as we speak
There’s no way Leorio could have a major role in an arc like this one
Personally I just don’t see how Togashi brings both of them back in time for them to make it to the DC. I think Killua will go maybe to find out more about Nanika/Alluka but I can’t really figure out what he plans to do with Gon
If there really is a New Continent arc then I think that’ll be more of a training arc for Leorio than anything. All speculation tho

Yh Killua has a reason to go to the Dark Continent…since Nanika is confirmed to be an AI from there. Killua loves Nanika very dearly as well. So yh something could lead him to go. And yh I just dont see Killua in the plot without Gon being with him. Gon is obviously too weak to go….thats why a 3-4 year timeskip would be great for him in training. Gon after finding his dad…has basically the same character arc as Killua. Which is finding something he wants to do. Togashi obviously bring him back and then we can see Gon discovering what he wants.
Anyways I think the “New Continent Arc” will be beneficial to end all the Hisoka/Spiders/Kurapika business once and for all. Thats of course assuming it doesnt end within the Black Whale. No way this this plotline carries on into the Dark Continent.
