And how would the mechanics of that work?

It wouldn't.

We already went through this, with all the litigation filed by the Birthers after Obama's election. All of their cases got thrown out on standing issues. The same thing happened in the Colorado case, AIUI - Trump tried to remove the case to federal court, and was shot down because none of the plaintiffs have standing for a federal claim.

Not every legal defect is justiciable by private parties, and it's highly unlikely that any person has legal standing to challenge the qualifications of a sitting President.
