Yes, but the whole premise of Stargirl, as is, is that there was the JL and her team is those whose powers came from devices that have now been passed on to others. The Infinity Inc series plan was to use the children/nieces-nephews who seemed to have been born with the same or similar gifts - Jade and Obsidian, Sand (who gets prophetic visions in his dreams like Sandman). Not sure who else they would have gone to get. Also, they setup Helix and some of the powered kids from there - Penny Dreadful, Tao, Kritter(maybe), Carcharo - led by Nurse Hope and Mr. Bones.
