Someone commented on that a short while ago. I think the gist of it was no, at least for the Animal and Machine tyye of cores, mostly because they were too complex and would take too much time to set up on the assmbly line, with a potentially high rate of errors.
But I see no reason why simpler cores like the Heat and the Equation couldn't be used.
However, I believe the new Track team is more concerned about matching cores to their new Ebonite-sourced coverstocks. All the cores seem relatively simple and all the coverstock are all so strong.
