I think this would be cool if somehow we had it so when you leave to the KitPVP spawn with said command, it stopped your killstreak but it didn't add to your statistics as a death (I assume that's what you're worried about, otherwise you would be suggesting that everyone gets /suicide, not just premium+); it wouldn't count as a death because no one is killing you, and you have a cool down until it actually excecutes the command.
