No, Devas do not count. After some massive re-fluffing, perhaps, but as-is? No, they don't fill the role of 'Otherwise normal person descended from a good-aligned outsider/someone whose ancestors made a bargain with the forces of good'.
Actually, this could be connected with the Nephilim idea that's being tossed around here. Instead of a seperate race for each plane-touched, make one big race for all that belong in a certain catagory - possibly expand genasi to include plane-touched beyond just elemental, so you'd have the classic tiefling or aasimar in there as well.
