While it's unknown how popular or how good the show is their is always a chance we will see new series regulars added in later years to either help win fans over or just for creative reasons. Now that we have seen a glimpse as to what the show will look like, which established characters do you think would fit in as a regular? Also you can't count Sarek or Mudd from this season. I got 2 off the top of my head.
1 Scotty: We know he served on other ships as a engineer and I think he was even Chief Engineer before Enterprise so it might be fun if Discovery was one of those ships. I would also be open to Simon Pegg playing the character because it's Simon Pegg and if you can get him you go for it.
2 Janice Lester: What better thing could the show do for "TOS" than to reform the character by making her kind of insane and maybe even a villian. Crazy is always a fun trope when it comes to villians and I guess you could go with Garth as well. Still it also serves the benefit of saving that final episode's, liberal butt by making the sexism go away and helping make her "No woman captain's" line and behavior in Kirk's body be that of a crazy person instead of from a writer who wasn't very progressive.
