Oh yes, it could.
Not with the show being out of production or Jen Lien not being fit for the part anymore, it can't.
Ah, that malice, that malice. Feels gooooooooooood, I guess!
Anyway, the lifespan could easily have been prolonged during the series with the possibilities I mentioned in my previous post. Not to mention that those possibilities still exist for future books.
The comment about "Jen Lien not being fit for the part anymore" was actually rude and unnecessary. In that case, very few of the TNG, DS9 and Voyager actors are "fit for any parts" in any upcoming series.
