Your wording lets me assume that you would welcome "Zolo kills Kizaru", right?
Going by the story line, there is still a little time for things to move on until Saturn and Kizaru arrive. What makes you think that the seperation of the SHP is final? Also, we do not know where they will disembark. It could also be that Kizaru will clash with one of the other groups first, before he can find Luffy.
I do not think, Zolo will kill Kizaru, but maybe he is going to have a few panels, in which we see them fight, who knows... .
