Wishlist Cart block

This module is quite awesome. However, I'd like to make it even cooler by integrating some of the cart block functionality. When items are added to the wishlist I'd like an expandable wishlist box something in the lines with uc pic cart block. I've been thinking that it should be possible to by adding some functions from the uc_cart module. Has anyone tried something similar or had similar ideas? Would be great if someone could point me in the right direction.
