Ravenclaw Wedding Officiant Looking for New Ceremony Ideas

Hey there r/harrypotter! I am a professional wedding officiant and confirmed Potterhead, looking to better combine the two! I get a fair amount of Harry Potter weddings each year (because I reference HP on my website) and they are decidedly my favorite. I have an original HP Handfasting Ceremony that invokes the "Unbreakable Vow", and a Unity Potions Ceremony (colored water and dry ice) that everyone loves. It would be a dream come true to become a sort of HP specialist in my field. What areas of expertise would you expect from such a pro, and what sort of ceremonies would you like to see offered? Thanks for reading and I appreciate your responses!
