The $64000 question is whether Congress gets to redefine NBC. If it does, then all this stuff is about as relevant as the buggy whip.
As with a lot of other issues. Giving the Congress the power to redefine the meaning of words in the US Constitution is just insane. It is an obvious short circuit of the entire amendment process.
Congress can't change the qualifications for the Presidency by changing the law. It doesn't work like that.
It requires a constitutional amendment to change those requirements. Nothing less will do.
