Sounds cool right ?... I think it should be an option on ether the golden gun class perks or in the celestial nighthawk exotic... You can ether have normal flames and shots with extra headshot damage or blue flames that turns the 3 shot into 1 shot with x6 damage and 6 shot into blue 6 shot that extends your super duration on headshots... It would be like how you can pick between 2 perks on surois.
