I know Vince Gilligan is just spit-balling here, and keeping interest up, but I think a Walter White cameo here would be awful. It was pretty well established on Breaking Bad that Walt and Saul had no history together. Even having them in the same room prior to their meeting on the show just screws that up. A Jesse cameo makes a little more sense, but would be logistically hard, since Jesse would be around 18 at the time this show takes place in, and Aaron Paul is obviously a lot older than that.
The cameo that makes the most sense is Mike. He worked for Saul and I thought it was clear from the show that those two characters had a good working relationship up until the end of Season 3.
