No, sadly G'nort has not been made.
You would have a hell of a time with the Legion. Not a single Legion member was ever released in the main line. Instead, Matty put out a twelve-pack of Legion members that has skyrocketed in price on the aftermarket. Starman was part of the Club Infinite Earths subscriptions, but again, aftermarket prices. He's a nice figure that could fit in either the Legion or the JSA.
JSA members shouldn't be too hard, though. Jay Garrick is the only one that fetches large aftermarket prices, since he was also a subscription figure.
