Excellent idea - she will not associate doing something wrong with not getting the rope but will quickly assocaite the correct behaviour with the rope.
Try putting it somewhere out of her reach near thedoor. Only when she has behaved correctly do you you reach for the rope and give her a lot of verbal praise as you do it - really happy, highpitched, excited voice. When she has not behaved correctly then you turn your back on the rope and give her the very minimum or attention to get her in. (A very quiet, calm, "Good girl" when she responds to the recall.) Once in she is ignored.
The contrast between the two reactions will encourage her to want the extreme, happy, play with rope reaction and she will strive to get it. - Keep it high energy and fun and she will WANT it!
