Harary conjectured that the set of vertex deleted subgraphs is unique up to isomorphism. (On the reconstruction of a graph from a collection of subgraphs. In Theory of Graphs and its Applications (Proc. Sympos. Smolenice, 1963). Publ. House Czechoslovak Acad. Sci., Prague, 1964, pp. 47–52.)

If you could find an example, you would have proven Haray's strong reconstruction conjecture false. This is because if the vertex reconstruction conjecture is true, then the edge reconstruction conjecture is true, thus the same would hold for the set versions.
