Personally, I see either the Star Vipers pilot or the Gabilani Pirate having the potential to be recruited.
The Star Vipers Pilot as a possible crew mate is due to the fact that when you bring her onto the ship and when you land at planets or locations she can leave, she seems to be reluctant in wanting to leave, so it seems that there is potential for recruitment.
The Gabilani Pirate seems more straight forward, since she doesn't immediately attack and will leave you alone if you pay her. So hypothetically you could recruit her under the pretense of a bodyguard or something.
