I don't think you can because when they accept you, they cross check everything including the email addresses on your recommendation letters: written by counselors, teachers and other people. They will verify that the teacher is a teacher and that the counselor is one as well, so I don't see how you'll find a loophole. It's better to write it on behalf of someone you know with authority, so that in the chance that you'll be accepted, your authenticity wouldn't lose you the chance. Hope this helped. Good Day!
