Notwithstanding everyone's enthusiasm and availability to start tomorrow, the fact remains, as explained a couple of times now, that there physically isn't the spare capacity in the training system to train NTR newcomers AND internal fleet transfers. The queue for internal transfers is rather long at the moment.
Training of new crews continues from internal sources whilst the recruitment is to augment the line numbers with minimal training burden. The next step I imagine, if not enough 787 rated people were to come forward, would be to take on 777 rated people for whom a relatively quick CCQ would be a easier win than a full rating course. In that instance, one could perhaps get 4 or 5 CCQs done for the "price of" one or two new full TRs.
