I think this would be difficult to retrofit. Currently, a cell and its neighbor are divided by a unique face which is characterized by its unique vertices which have unique coordinated. Your scheme violates this since you'd either have two faces, or one face with vertices with multiple coordinated. It's a good question in how many places we use this invariant, but I'm sure you'll find all sorts of places like these...
