You forgot that Janeway and the Doctor also made an appearance in William Shatner's Captain's Blood (2003) and Captain's Glory (2006) during the Totality incident.
But the Totality trilogy contradicts other aspects of the Trek Lit continuity, particulary where the timing of events in DS9 and Titan is concerned. So it's not part of the same continuity as the VGR post-finale novels.
Of course with the Voyager Season 11 books it'll be interesting to see if Voyager also revisits races that were encountered in the novels.
"Season 11?"
