"Tempering" as a concept is a fairly new thing to happen in Eorzea, so a background of previously praying to Garuda seems plausible. It wasn't until the primal herself could be summoned that she would have tempered/touched/what-garuda-does-to-temper-something-ed minions. But as we've seen with the story, there are usually two factions of the beast tribes. Those who were tempered and are effectively mindless worshipers and those who are not tempered, but still revere their diety.
OOCly: A weird, but interesting concept.
ICly: You'd probably get some very bizarre stares from people, especially if you preeched it out loud. Ones who are more fearful could very well think she's tempered and shun/do-worse-things to her. Remember, she'd still have to show this at some point because people are not (or should not be in most cases) mind readers. What your character does in private should remain private.
