I think you have a good pattern going here when you classify things as "things you'd say to a..." Maybe, outside of the ritual itself, people could volunteer to be one of those positions for others without those services. Like, the Moombah would be the guy that listens to the things you'd say to a priest, without being a priest. He would listen under an oath of secrecy, to anyone who wanted to confess something. The High Glombix would listen to all the things you'd say to a therapist, without being a therapist, again under secrecy. The Vemerev would listen to all the things you're afraid to tell your friends about yourself, without judging you. It would be an accepted support group without relying on the traditional avenues, and it would also serve the purpose of getting you used to evaluating yourself and to verbally admitting your problems.
