No, that's actually impossible. Many/most of the core packages are dependent on systemd - directly or through intermediate dependencies. If that weren't the case - there would be no motivation to fork the distribution. Part of the arguments that led to the fork was the "viral" nature of systemd use, i.e. it's not just an opt-out option, but more integral than that. At the same time - breaking the systemd dependency was not extremely involved technically. Very little code had to be written, and most of the work is tying things together at the distribution level.
