For Season 3 of Supergirl and Legends, along with Season 4 of Flash, and Season 6 of Arrow? Yes. However the past seasons of each of the respective shows were much better about the universe connecting even without a crossover happening. They even had Supergirl have mini-crossovers and references such as Dead or Alive on Flash.
