Shower thought re: MAGA and the Pope

So, I was showering the other day, and a thought occurred to me, and I got to wondering what others might think about MAGA and the Pope thing.

To put it simply, it occurred to me that Trump might decide to pull a "Henry VIII" and demand Catholics in and out of the Administration (particularly IN the admin) declare allegiance to him and not the Pope. Unlike Henry VIII, Trump is not Catholic, but he does have unchecked hubris, so I can totally see Trump doing this.

Historical background, VERY simplistically reduced down:

When Henry VIII wanted to marry Anne Boleyn and divorce Catherine of Aragon, the Pope would not grant him the divorce, so Henry broke away and then demanded everyone swear allegiance to him as "Head of the Church" in England. He got his way, for the most part. Some people refused and paid the price and lost their heads, most notably Thomas More, who was canonized at some point as a Saint in the Catholic church.

What do you think the notable Catholics in the Administration will do? Will they care? Will the decision be difficult? What if Trump decides to name himself as "Head of the Church (all churches)" in the US? I mean, we already have Vance and Homan saying the Pope needs to butt out of shit, with Homan offering to teach the Pope theology, so I know with those two in particular it's a no-brainer. But what about the Cath-MAGAs at large?
