Dixon would be worth a crack at. Good size and can play, but like Andyy said, probably not quite enough to get into a bidding war over if that's what it came to. Was a fan years ago and Dio has been suggesting it recently, McKenzie would be my pick of the bunch. Not so much as a stopper, but plays great loose/intercept/3rd up behind the ball, can actually run and break lines and has a booming and left foot.
