It has the potential to be overused, although it could be useful in a "big ship" sense, where characters play both the command crew and department heads of a capital ship or civilian equivalent, and crewmembers within each department.
During one scene, the bridge command crew could be engaging an enemy vessel; in the next scene, the characters are an Engineering repair crew, or medics in Sickbay tending to the influx of casualties and performing triage, etc.
Different departments, different stories and conflicts.
