I don't know. That's not a solution that appeals to me. And I doubt it would convince anyone. Blasey Ford has already taken a polygraph administered by a former FBI agent. Has that satisfied any Republicans?
What's needed is a full investigation.
But even with that, there'd still be problems. As someone on TV just pointed out, the cries for "due process" are irrelevant, really. This isn't a trial; it's a a job interview for Kavanaugh. People get turned down for jobs for all kinds of reasons.
