Rick, I'm not an expert, but if that were my plant, I'd cut it loose. With winter coming,
root growth will slow down. Once it hits, those roots are going to be
exposed to the elements, with little insulation.
I might pick off all but the top leaf from each branch of the air layer, cut it,
pot it, and bring it inside, to a bright window. Another six weeks of constant
70-75 degree temps would give that plant enough time to settle in.
