It is about ratio. If I remember correctly, if you were attaching the binding to the back first, you would need 1 5/8 inch wide flange colour, and 1 3/8 inch wide main colour. So theoretically, if you reversed those numbers and attached the binding to the front first, it should look the same. Of course the flange will be 'floating' because you said you wanted to hand stitch the binding to the back, but it should still give you the look you want. I would try it with scrap fabric first.
