That's the problem: female heroes that weren't created as a distaff counterpart, sidekick, or to fill up a team for PC purposes, are scarce. Wonder Woman, maybe Black Canary. Phantom Lady and Liberty Belle, but they're not well known. Like Oknight said, there was simply no market for new female heroes. Only two female heroes headlined their own title in the Silver Age and Bronze Age: Wonder Woman and Supergirl (the latter did not last long), and both had a female hero in the backup feature (Huntress and Zatanna, resp.). Female heroes might occasionally have had a feature in Detective Comics or Batman Family/Superman Family, but other appearances were only as part of a team or with a male hero.
