This might work, in combination with something that I see others have suggested. You need some way to get them to listen. This would take a lot, given that they’re already recording the verdict. So: would the threat of destruction goad a dementor into breaking through two animal Patroni? Can Harry believe this would happen? (If so, coldly claiming that he can destroy Patronus ability might create enough doubt in the others’ minds that it wouldn’t matter if dementors follow expectations or not.)
This plan does have shortcomings, like the threat of killing someone’s mind (perhaps even Hermione’s) and the risk of revealing what he did in Azkaban (at least to MoR!Dumbledore).
Harry knew another patronus was seeking his own patronus, so I think he should at least know there’s a risk that someone might be able to identify him.

Harry doesn’t know of this risk. If we’re modelling harry we should discount it.
