I think if you create the shaping by doing short rows...which in themselves stack the shoulder higher closest to the neck...but doesn't cast off the stitches while you are doing the short row shaping...then eventually when you have created the gentle stacked shaping you will have all the original stitches still on the needles...and then you could do the 3-needle bind off.
Boy, did I say a lot and communicate nothing? :??
Someone else will weigh in on your question, too!
