Ro Laren was originally planned to be the 1st officer on DS9. However, I think it's better that she declined to be in the series. There would have been 1st officer on the station that had disobeyed orders and people had lost their lives because of that.
Putting an officer with that kind of history as the second in command of the station would have been silly. She got her "job" back too easily in TNG? They needed her help on one mission and suddenly she is flying around on the flagship. Besides, I think Nerys was far better character. We didn't get to know Ro as well as Nerys but still.
