I agree with the pp - the name is a bit much for me personally (I'm more of a traditionalist when it comes to names), but I prefer the spelling Ary or Airy.
I would, however, like to point out that I would pronounce these two spellings differently, so you might want to take that into account and choose the spelling that correlates with your intended pronunciation better (since you don't have a preferred spelling, I assume).
I would pronounce Airy and Aerie as Air-ee. And I would pronounce Ary as Ah-ree (like Aria, but without the last 'a').
That being said, I would probably choose the spelling 'Airy', since you probably want it to sound like 'legendary rhymer' (I apologize for my assumptions, if that's not the case).
