Of course if you fail CBAT at a later date then your future branch choices are obviously going to be limited. But otherwise, I'm afraid you're out of date with the way an airman potentially changes branch to WSOp. He no longer needs a recommendation from his CO; nor does he even need to have been in long enough for any SJARs. He can just walk into the AFCO like anyone else! And there are very few roles from which he might be prevented from leaving - that would be a career foul.
