This is the very reason why Hydaelyn fighting Zodiark through WoL actually makes no sense. She's so weak that she actually brings nothing to the table in that scenario. In order to fight she would need a huge amount of aether, and if she's unwilling to draw upon the star's aether, there's basically nothing she can do in her current state. Meanwhile, whether or not Zenos is Venat, his ability to override the will of Primals could lead to him mantling Hydaelyn and using her connection to the Lifestream to gain almost infinite power and threaten the very survival of the planet.
The issue with the Zenos-as-Zodiark idea is that it's contradictory with what we know about the position he's in. Zodiark was sundered like everything else and locked in the moon, it's arguable whether or not he's cognizant, or even "alive". The Ascians have spent 12,000 years working towards his resurrection through the rejoining of the Source and shards, so how exactly is Zenos supposed to just become his new heart and suddenly he's both free and got the power to threaten the world? If that was possible you'd think the Ascians would have done it by now.
