Sadly this is already settled law as of March of this year.
The Supreme Court case Trump v. Anderson ruled that states do not have the right to determine eligibility for federal office.
A state could bar Trump from being elected in a local election or being appointed for a state office, but do not have the right to declare him disqualified for a federal office based on state laws, or even a state's interpretation of federal law.
Lucky for him that his first term allowed him to stack the supreme court and make this ruling possible. Imagine what his next term will bring.
