There was only one definition of natural born Citizen at the time the Constitution was written

While I might agree with you that the Vattel concept was what the Framers had in mind, you are either dreaming or ignorant of the other usage examples including ones in England and in the Colonies. Any court could reasonably decide this issue however they wanted to decide it.

England had no Citizens, only subjects.

Again, the term natural born Citizen had only one definition at the time it was written into our Constitution.
