I doubt they'll let the Supergirl characters be too involved however Nora did mention Lightning Lad and we know the world merge happens when Barry vanishes so I have to wonder if she's working with one of the members that aren't Brainy, Imra, and Mon-El. That would explain why she knew about the chip and the satalite.
