Yep, I like that idea. I have one of my own. Bring out the full weaponry of the First Amendment by making your wedding business a Heterosexual Marriage Advocacy Organization, in which each heterosexual marriage is a deliberate protest against the decay of traditional values and an intentional affirmation marriage as God designed it to be, between one man and one woman for life, just as Jesus said.
The legal angle? Right here:

In HURLEY v. IRISH AMERICAN GLIB ASSOCIATION, a Saint Patrick’s Day parade was allowed to exclude gays despite the typical public accommodation ploy because it would be impossible to convey the message of the group if they were compelled to accept participants clearly at odds with that message.
So rather than go hide under a rock somewhere, Christian wedding businesses need to go all in on free speech, make that an explicit part of the business charter and model, that the main purpose of the business is to advocate for heterosexual marriage, for profit. The Hurly vote was 9-0. Just sayin ...
That is wisdom. Wise as serpents, harmless as doves
