If the main reason Lane doesn't cover for Copeland is that she no longer dances with Cornejo (which I know we don't know — why I say "if"), then I don't think it's less likely now than before. There are other potential SL partners for her.
That said, I already thought it might be rather unlikely, even if she were still dancing with Cornejo.
ETA: Actually, now that I think about it, if she's no longer dancing with Cornejo that does probably make it less likely. When Copeland (likely soon) retires O/O, Cornejo will need a partner, and they might have turned to Lane. You're prob right, Lena C. And yeah, bums me out too.
