I think it would have been great if they could have had Steve Urkel crossover to an episode of Perfect Strangers (the show that Family Matters was spun-off from in the first place). He could have taken a job in one episode as a messenger boy or something like that in the newspaper office where Larry and Balki worked - the interaction between those characters would have been hilarious. :)

Yeah that would have been funny. I was wondering, did the ever mention Harriette after she left PS.
