Certainly possible. When we first see Zodiark shackled on the moon, even in his incomplete form he is absolutely terrifying. When he is broken free, and he just kind of phases out ala Gozer without so much as a wisp, I got chills. So I figured Hydaelyn's design would be in direct contrast to that, and be one of beauty, security, and comfort. I think that is what they had in mind more so than what would Venat look like in her transformed state.

When I think of Hermes and Hades, they bear little to no resemblance to their ancient forms. Hydaelyn however, very much retains Venat's signature features, especially her eyes.
