New Game Type, Similar to One in the Chamber

I was thinking about a sweet new game type that I would like to see 343 put out. SWAT rules, as in no shields, no radar, one shot head kill, maybe something like FFA with 6 players. But instead of a full clip, you only get 5 bullets for the DMR or Pistol. When you die, you do not spawn with a gun. You can either go find your old gun, or sneak up and kill someone and take theirs. It would be a slower moving game, so smaller maps would be preferred. What do you think? Any changes/Mods?

Instead of spawning with no gun, why not spawn with an empty gun or a gun with one bullet? Just my thoughts.
