It is more likely that the latter will earn the killing streaks, becoming even harder to kill if it gives bonuses to stats.
Perhaps, it could be done to have visual effects on your character instead? Add to that the feel-good factor generated from earning killing streaks, and this might work.
Just my thoughts.
