Further speculation and erstwhile hope: might a time displaced Trip possibly appear?

edit: so, upon getting home, there is now an update to at least part of the film’s content taking place during the “Lost Era”

From Memory Alpha: The “Lost Era” concept was developed by Pocket editor Marco Palmieri, who defined it as the period of history between the apparent death of James T. Kirk aboard the Enterprise-B in 2293 and the launch of the Enterprise-D in 2363 .

So now if nothing else, we have the inclusion of a younger Captain Rachel Garrett of “Yesterday’s Enterprise” fame.
