I'd say it would make more sense to do it with the strangers rifle over the khostov since everyone has/had that gun. Not everybody could have the strangers rifle if they didn't care to complete the campaign (you have to complete the campaign to get it).However, it would be very mean and stupid of bungie to release something like this out now knowing a ton of the players have dismantled one or both due to so little storage space they won't add more for... Like the idea though!
