I wonder if someone gave a moment's thought to a spinoff. With this cast of crazy money grubbers, each with a unique personality, it may have worked, especially with a juvenile audience. Quark's mother is taken prisoner by the Dominion and he and Rom come up with a plot to rescue her, employing friends and relatives. Of course, the whole thing is ludicrous, but as a stand alone, it works pretty well.
