I don't know if you can make big changes to characters in Trek Lit without having it all be pointless when the next novel's released. Not that I'm saying you drastically altered Picard or anything because you obviously didn't. But how does that work? Can you monkey with these people at all? I know that the editors work out the big plot beats a few novels in advance but how much obligation does the next guy have to write Picard consistently with how you wrote him in TSW for example?
That's the editor's job to keep track of. But as far as I know, the next person writing Picard/TNG is Dave Mack, and he and I tend to compare notes on our Trek projects pretty regularly. In fact, I daresay I was pretty much following his lead from Destiny
when it came to exploring how parenthood has changed Picard.
