Wasn't it Boxhall that woke up the other officers? I think Geoffrey Marcus implies that in "The Maiden Voyage," though I don't know what his source is.
Based on Lightoller's observations in his memoirs, I would be inclined to conclude that a meeting didn't happen because it wasn't necessary. Consider the his statement:
"Discipline in a merchant ship calls for the highest display of individual intelligence and application. Each man must think for himself . . . If a man does no more than he is told, and makes that an excuse for leaving something undone, unseen or unattended to, he is quickly asked, 'what the hell are your brains for?'"
I would suspect that Boxhall gave Lightoller slightly more specific instructions as to which boats to swing out (i.e. port side, forward) when he visited Lightoller's cabin. Once he had received those instructions, there would be no need for Lightoller to report to the captain--he knew what he needed to do.
As for the junior officers, Pitman went to the bridge after he was awakened (I believe he went down to the forepeak first, though). Lowe testified that he crossed to the starboard side after leaving his port-side cabin; I should think that the bridge would be the most convenient place for him to do so. Assuming that Captain Smith was on the bridge, he could have dispatched each officer to his duties individually. Boxhall, Moody, and Murdoch could be similarly assigned as they were already on watch. That leaves only Wilde, but my memory fails me at the moment and I don't recall if Boxhall specifically mentioned passing by Wilde's cabin, but it seems to me to be a safe guess.
Holding a conference under the circumstances would have been a waste of precious time, and Captain Smith knew this.
