You should definitely try! Like I said ... I believe it can work. As long as one person wants to save a marriage there is hope
I think this 180 degree system works because if you push another person for reconciliation they push back ... by pushing away from you. So, by taking a step back you give her the space to see more clearly, to stop being defensive, and to show her that you are the man she first fell in love with.
Good luck to you!
