Tricky, of course there is no pretence of Holy Spirit being involved any more. The CS does the appointment, it is no longer rubber stamped at Bethel, they are not even informed. I think the way to go is to drop little facts like those in and let them fester. Incidentally we had one poor sod appointed as an elder and then removed within 10 days. Not much evidence of spirit there.
You don't have to mention the HS, just the new system fo appointment , let her work it out for herself. She may tell you what you are trying to tell her.
