Two events Swat mode and a Kraber 50cal?

I used to play a lot of Halo back in the day. And abit of COD mw 2. Played a lot of Swat. 3 shots to the body for a kill. 1 to the head to kill. Could perhaps only use the wing man? 

and for the kraber 50cal event could be abit like custom games no scopes with the bolt action sniper. In the good old days of customs. 

Any one up for this? Not sure what skins should go with it. Perhaps halo theme for the swat. And cod theme for the no scopes?
