I'd be interested to see some sort of legal authority for the idea that #2 would ever be a possibility.
I'm also not sure that a refusal to adhere to #1 would result in impeachment -- or even support impeachment. Again, the President's obligation is to support and defend the Constitution; in so doing, he is to faithfully execute the laws. But the executive branch and its agencies are alleged to have violated laws frequently and are sued by individuals who would be protected by those laws for those violations. Those suits are how the constitutionality of the law is frequently determined. Sometimes it favors the executive choice against enforcing a law; sometimes it favors the claimed right of the individual and sanctions the refusal to enforce the law.
Ultimately, our system of government would be hideously more ineffective than it already is if every disagreement between the Congress and the President about the putative constitutionality of any given provision of a law could become the subject of a pre-emptive lawsuit.
