Redshirts RPG

So, I've been reading John Scalzi's Redshirts. Generally about the poor sacrificial crewmen
  and thought it could make a fun little RPG, along the same lines as Puppetland.

Ideas so far - this is just ideas. Not a fleshed out design:

• 45 minute "episodes" (maybe with commercial breaks but I haven't worked out the mechanics of that). More about the story than the dice.
• All player action is in script form. You either speak, or refer to yourself in the third person to give character direction.
• Merits/flaws
  • Comic relief - Gives some sort of bonus to character if you make players laugh.
  • Non red shirt - Doesn't actually improve chances of survival, but still costs a point.
  • First name - Increases your chances of survival.
  • About to be married/about to retire - increases chance of death.
  • "You just had to say it" - Tempts fate by speaking.
  • Mary Sue - annoyingly perfect.
  • Relationship with series regular - at risk only when away mission includes series regular
  • Played by famous actor - no idea what this does.

Thoughts?
