There's more ways to do a break up than by business function. It might make more sense to just divide it all down the middle to create two successor companies (e.g. one gets half the warehouses, and the other gets the other half). Then you have two peer competitors with all the skills, knowledge, and culture to compete viciously against each other.
The biggest issue there is which one gets that branding, which I think should be solved by neither getting it. They should come up with new identities, and amazon.com becomes a simple ecommerce directory.
