It's pretty unorthodox but meh.Eh, this is to help rebuild the relationship between the CPO mess and the Wardroom.
It'll help a lot if everybody is straight on the ROE, not just what behavior is unacceptable but more importantly what behavior is expected- if the Os and Chiefs are too hesitant to mess with each other at the thing then the whole affair will be stuffy and boring waste of time...
Speaking of which- don't forget to put out your ground rules about cellphones and cameras! (i.e. Don't bring them in unless you're on duty or the CO.) Plus one or two "by-laws" for anyone who screws that up at the event.
