mw2 killcam/final killcam

Is it possible to make a mw2 style game/round ending killcam?
And a menu to set how many kills required for this?
Aka:
Kills: 25/30/50/100
Do you want this to work? (Button)

I also wondered this and alot would have to be done, but I think this would only be possible for the ending killcam before the game changes map because you don’t want everyone to see the replay while they are still battling… wait… unless clientside rendering of models and animations, but that would include alot of storing data constantly by the server or a better way by the client and some client computers just can’t handle that immense amount of storing data. I’ll look into it some more, but I’m more on the doubting side.
