I would say so. I imagine it would mostly be logistical details, reconciling what the combined force is made up of, and exchanging knowledge in anticipation for battle plans. If you wanted to play out a meeting where a specific point is addressed, you could do so. If they're being provided propylon stones, though, there may be some extra officers snooping around to get a closer look at them. It's very strategically powerful magic that Meesei is revealing there.
