Honor Harrington: Puke was talking about this at one point, don't know if anyone is working on it though.
Starfire Universe: Pres Elect Shang was talking about this boardgame (if I remember correctly) that was the inspiration for SE IV, would be fitting to be added at some point
No work on this as far as I know.
Battlestar Gallactica: Cyclons and Colonials are both viable, though there aren't any special weapons for them as of yet.
Andromeda: Someone mentioned this in passing, but nothing has been said about it since.
