Simply Put, Your Racial Features should not Disappear.

Makes it much more neater if your racial features get voidsent traits.
Like Miqo'te/Hrothgar Ears and Tails Get more Feral. And Hrothgar and Moonkitty fangs are noticeable.

Au Ra Scales And Horns Get Unnatural effects.

Lalafels can morph into Tonberries(Semi-jk)

As for Elezen can Become more Castlevania.

And Hyur/Roes just Become the Poster Child of a Well Built Reaper, or skeletal reaper.

As for the Topic of Seraphism.

I like the Concept, No it does not go against what scholar is. (If anything You can View it as A Fairy/Angel/Winged Creature of KNOWLEDGE/TACTICS)

It's basically Being True to what Fairies Are.
While WHMs have always been with the Elementals (Thus their More Connection to the elements. But also Inadvertently, Stasis/LightAether.)

There is no Conflict here.

While Seraphism could be represented in a better way, maybe have a Seraph Glow on the wings, or the whole body(lightly) its alright.
