I can kinda see where you are coming from, but I think you are oversimplifying it.

I think there is a somewhat unavoidable overlap in the aesthetic design of White Mages and Scholars. To me, they are both somewhat nature-focused. White Mages certainly are what with their communing with Elementals and their concern with the natural flow of aether and the creatures that interact with it. But similarly the Scholars have a nature themed identity with their association with Faeries and perhaps maybe Fae folk in general.

I think there is room to allow Scholars to have their Seraphism as an ability where Lily enchants you with the blessing of Fae folk, but I do agree it does look perhaps a bit too angelic at first glance. I don't think White Mage has a monopoloy on that kind of design. Hell, with the exception of limit breaks there is nothing that really gives White Mages that identiy except sorta maybe Temperance.
