I think it would be quite labor intensive and expensive. Look at your bag and all the stitching that would have to be taken out and redone. The lining of the flap would even have to be restitched. And I am betting unless you have some kind of pull with H, they would tell you they will not do it.Hmmm....I wonder if I could have it changed to a single at Hermes. It doesn't seem like a difficult fix. Has anyone tried this?
