No, because when you are on a layover, you are not in base, and X-list is in base only. You can put yourself on the Y list for where you are, and change JRM to your actual location, and they might call you. But they are only supposed to do that after they exhaust all other options pretty much. Having said that, they will probably just reschedule you if they need to, because "you are legal 117" (ask me how I know). Definitely grieve that if it happens...
