A Le Rhone,
Your lack of knowledge on what exactly a S/O or Crz F/O is, and more importantly where they have come from, shows without a doubt that you are not a recruiter for a 'proper airline' as you say.
That having been said, if you are actually a recruiter for an airline, I would be surprised if a S/O or Crz F/O would look sideways at your airline for work once they had been offered a position 'back home'.
FYI, on my S/O course (a long time ago now), we had 2 ex military instructors, 2 experienced regional airline drivers, 2 experienced flight instructors and 2 cadets.
