It appears what we need is more like Great Britain. A monarchy that can preach, talk, and say what ought to be (“that’s not who we are” over and over again) but can’t really interfere too much, and a parliament that gets “stuff” done.
The monarchy could in theory be as corrupt as it wants personally and professionally with little harm to the Republic. If people want to give “gifts” to Kaine or the Clinton Foundation, or pay for speeches, so what. They wouldn’t be able to peddle influence any way.
