Rielly looks like he could make the transition to me. He'd have some growing pains but seems like he'd learn a lot and pretty quickly. Love his skill set.
Gauthier looks like he'll be a 3rd liner at best (though he could be a really good one), Raymond should make the team, Biggs unfortunately looks like he'll be a bust, Ranger will probably make it.
Liles and Franson are questionable IMO as Phaneuf, Gardiner, Gunnar, Fraser, Rielly and Ranger could prabably get the job done effectively (and much cheaper) over the course of the season. Not the worst problem to have.
