Dooly, Tom, Adam and Lasse are certs. I think Kozza could do with a year away so bringing back Schrammy or Sanchez is fairly certain - both would help beef up the team away from home.
Wouldn't like to pick the final 2 - most of the obvious choices have already been mentioned, but would think Poole, Davies, Kerr are unlikely as we wouldn't get them away from their current teams. J Lo would be a risk after his big accident then year out. Eklof with the right head on would be a good choice, but would also be a risk. Not sure what average Christian Henry is on, but he ought to be a consideration as well if he is still riding? Maybe even Millsy on decent equipment...
