If Venus is meant to be Zoro’s final opponent, then Oda has written himself into a wall by having them clash now.
Now that Zoro knows about Venus, saw his blade, and clashed with his haki — he should have a general sense of where Venus stands power-wise. Especially if they go on to clash even more in the upcoming chapters.
This means that
if Zoro believes Venus to be stronger than Mihawk, he will go into the Mihawk fight knowing it will mean nothing for him and knowing that he won’t actually be the WSS even if he wins.
So it’s either Nasjuro has been disqualified from being Zoro’s final opponent, or even if he is Zoro’s final opponent he won’t be stronger than Mihawk.
