Kindlebooks don't use xhtml to display the cover image. They use the image itself (defined by OPF properties). So it doesn't matter how an image is wrapped in the source epub; a kindlebook is never going to display a back cover image in the same way the cover image is displayed. There's no way to code the source epub so that the kindle conversion process can be "tricked" into providing a feature it doesn't support.
