I don't think that Supergirl would be too difficult to introduce. With an alien invasion and Superboy and Superman reconciled, Season 2 would be the perfect time to introduce her and bring her into the Super family. I'd imagine that all of the space battles would bring her ship to Earth, where the YJ team would find it during a mission, free her from her ship, and bring her to the League and Superman. Then, after learning English and training with her powers, she would go into the family business and serve as an ally to YJ and a substitute for Superboy if he goes out of commission.
