What would an American “king” or “queen” be called. Assume those titles are too offensive for American senses [closed]

This is purely hypothetical, of course, but here's my quick scenario:

Assume the people of the United States voted to install a royal family, one that had no power, and was purely ceremonial. But, according to true American sensibilities, this family cannot use the titles "king," "queen," or "emperor."

What suite of titles could be appended to such a family? Something inoffensive, yet still evincing a sense of wonder. ("power" is not the right word). Something unrelated to English titles, is what I'm thinking. And titles that avoid sycophantic-type treatment. Any thoughts?

Added clarity: The current government structure of the US remains the same. There is no transfer of power to this new royal family. They are created within the US Constitution (by amendment), but exist within the current political ecosystem.

• @papelr, we apologize, but Stack Exchange is a Q&A site, not a discussion forum. Seeking opinions is exactly what they don't want anybody doing. This is why one of the reasons to close a question is because it's primarily opinion-based. Read though this specific Help Center page to better understand the limitations Stack Exchange has asked everyone to live with. Thanks. – JBH Feb 24 at 19:12
• Not entirely opinion based. Sure, we còuld call him the Grand Poobah. America has already had kings (HM George III being the last royal king), and Washington's coronation at Philadelphia must have been quite the spectacle. (Don't worry, it was a crown of laurels!) Otherwise, google Norton I, Emperor of the United States. Tradition is very important, even in the USA. And no, those titles really would not be that offensive at all. – elemtilas Feb 24 at 19:15
• They called him Emperor of the United States and Protector of Mexico, Norton I. Yep, there was one ! – StephenG Feb 24 at 21:50
