In a limited way the game already reacts to a Cmdr switching ships - if that Cmdr is considered a criminal. I don't think mission-generated NPCs won't appear at least for some time after a ship switch. Missions could suggest changing the vehicle midway.
But to increase the usefulness of this, typical mission distances and the potential aggressiveness or number of persuing NPCs.
