You make a good point about the possibility that Maggie may have very well been written out after all the characters that were connected to her were no longer on the show. I agree that seems like it could have been a real possibility. If so, KLS definitely benefited from Alexandra Moltke's departure because otherwise KLS may have found herself without a job. Well, unless it was simply Maggie who was written out but they may have brought KLS back as a different character...
Another fascinating point is if Maggie had been written out of the show and KLS had not been brought back as another character, would Maggie/KLS have appeared in hoDS? Or would Vicki have been the one to resemble Josette as they did in the '91 Series?
Also, it's interesting that the subject of Betsy Durkin has been revived at this time given that her final DS ep is currently featured in the Robservations slideshows:
