IMHO, Kate Jackson would have been perfect as a replacement for AM as Vicki.
After reading all the posts in this thread, I started thinking that it might be wild if one year at the DS Fest, they had a celebrity panel featuring Betsy Durkin, Carolyn Groves, James Hall, Diana Walker, Mark Allen, and the original Matthew Morgan, whose name escapes me (is he still alive?). I wouldn't be surprised if they had some interesting stories to tell about their experiences on DS.
