Perhaps I should be a little more careful with my wording. From what I remember, it seems the discussions were about bringing her in from the second season onward. I think that In the Hands of the Prophets may have been an attempt to justify her permanent presence in the stories. She might have been a target for recurring tension on the station.I cannot confirm that there might have plans for her in the regular cast. That said, the scenes with the O'Briens in A Man Alone were actually written for the pilot: Piller, at least, was not thinking of her as part of the decoration.
