The answer is what I did. Buy a very good one off the bay. Tell her you bought it to modify into a bike bag, but if she wants it, you would love to give it to her and then get another off the bay. There will be no complaint, just complements about your good taste and ingenuity.
Very Smooth!! I'm off to try it.
