Will Luna Lovegood duel Alecto Carrow in Harry Potter and The Deathly Hallows Part 2?

It's just that in the first trailer where Snape vanishes into smoke, Alecto Carrow's body is laying on the ground near Snape. Will Luna duel her instead of just Stun her like in the book, i think it would be so cool to see Luna kick butt. : DWill Luna Lovegood duel Alecto Carrow in Harry Potter and The Deathly Hallows Part 2?
