I wouldn't do it. You have enough Goalies. I would hang onto Ryan. Kessel will barely be fantasy worthy this year and even if the goalie plays, which there is a good chance that he will not, he won't do much in the way of points as LA probably won't win all that many.
I would wait at the very least. Ryan will get a bunch of points, Kessel will still be injured and Toronto will suck, and the goalie still not playing in the NHL, that will give you leverage for more should you still want the deal.
