Leeds United are linked with the 26-year-old defender.
Clubcall reported this week that Leeds were interested in signing the Huddersfield Town left-back on loan when the January transfer window opens.
Gaetano Berardi and summer signing Vurnon Anita have been sharing the left-back role this season following Charlie Taylor's move to Burnley in July.
Berardi is naturally a right-back, while former Newcastle United man Anita played a number of different roles during his time at St James's Park.
And Redfearn believes that a move for the 26-year-old defender would add "natural balance" to the Whites as they chase Premier League promotion.
Asked on Radio Yorkshire whether a move for Malone made sense, the ex-Leeds boss said: "Yes, as it would give you natural balance and that’s what Leeds are lacking at left-back."
Malone joined United's Yorkshire rivals in the summer but is yet to start a Premier League game for David Wagner's side.
The Whites are back in action on Saturday as Christiansen's side host Reading with the hope of bouncing back from a tough run of form which includes three defeats in four games.
