The theme from Heavensward has to do with floating land masses, flying, sky type things. A race I am thinking of is similar to Revanant Wings' Aegyl. Adding an angel or feather winged type race could easily fit the landscape of Heavensward. We already have tails, pointed or fluffy ears... feathered wings could give a unique variety of features in the current playable characters list.

I know Viera and a draconian race, like Gria, have been talked about as possible future races. I think adding something like Aegyl, along with those even, would be a fun idea.

Some of my ideas are as follows:
*Could be connected to the Ixal or could have shared the Ixal's or Moogle's skyward homeland.
*Live in a City found upon the floating land masses
*They can be their own mount, using their wings to fly.
*Customizations can include wing color, feather type, wing shape.

I write this post in hopes it reaches the eyes of the developers and for others to comment.
