No, just the opposite. StopAndKill removes the original track, and _replaces_ it with the list of secondaries you add to G4ParticleChange.

Definitely don't add the primary particle back onto the list. You do want to set the track status.

If you're really meaning to implement a hadronic "model", then you should inherit from G4HadronicInteraction, and use the "RegisterMe()" function to attach your model to the appropriate InelasticProcess when building your physics list.
