I think a far more enigmatic and starkly ironic ending would be that he is slain while defending a child. That child then bears a mark from an attack which kills or nearly kills the attacker. You could then infer that the other characters "resemble" Griffondor, Hufflepuff, Ravenclaw, making their own -- new school of magic and the cycle continues.
