A modular hall of justice with Batman (he's in almost every set), The Atom, Hawkgirl, Alan Scott, Jay Garrick (I know these weren't the flash and lantern that were in the super friends but I feel like the super friends came out when there was little moral ambiguity among heroes both Scott & Garrick have had very little publication of being anything but moral heroes), Jayna, Zan. Basically it would just be a smaller (but to scale) version of the hall of justice with some thrown in play features or some small references to the super friends like some artifacts relating to other characters like Samurai's sword, aqua man's trident etc.
