Mass Effect 3 [request] Import Geth Spitfire Riffle to Single Player

[SilverAxe001]

When playing MP I really enjoyed using riffle Geth Spitfire. I ask for importing this weapon to single-player game.

 

Another thing, M-451 Firestorm was my favorite heavy weapon. If Geth spitfire was turned into assualt riffle, can somebody turn Firestorm into shotgun and make it usable in single-player game?
