However, if we have Federalist papers or other writings from Hamilton or Jay or Jefferson about how "natural born citizen" should be interpreted, then I'll take that over my Article 14 approach.
Let me give you some hard information on how to interpret "natural born citizen" in Article 1.
This is a page from a Pennsylvania Law book published in 1817, and is described as being based on the report of the entire Pennsylvania Supreme court in 1808.
Philadelphia was the site of the Constitutional convention, and many of the judges on the Pennsylvania supreme court were participants in the process of creating and ratifying the US constitution.
These judges know better than anyone what was meant by "natural born citizen".
*THIS* is purported to have been written by James Madison, but so far as I know there is no absolute proof of this.
It is written under the pseudonym "Publius" which is a pseudonym that Madison used extensively in writing his portion of the Federalist papers, and the entire article contains information that only the President, or someone very close to him would know about this particular case.
It is a high probability that it was written by James Madison.
