Wonder Woman and Batgirl came to popularity through a primarily male demographic. I have trouble seeing how trying to bring interest to these characters by tailoring stories for an uninterested demographic would help sales.
It's been quite clear to me that the comic book industry has been trying to penetrate the much more lucrative novel industry, which has a predominantly female audience, for quite some time now. Instead of working to foster and grow their core readership, they look for viewership from uninterested demographics. If they want to attract interest from other groups, they should bolster their main demographic and allow the fans to sing the praises. Right now, negativity abounds, and that's hardly going to attract interested readers.
To answer your question, I'd simply remove the writer and editor from the series--perhaps even fire them--and look for interested talents to take over. I'd be looking for someone with a vision and a passion to captivate an audience. Hell, I'd even take over the editing and writing positions, if I could.
I would also note that I'm not advocating for the tailoring of stories for one demographic or another. A good story will always attract an audience, but tailoring a story will come across as shallow and lacking substance. The DC and Marvel of old wrote entertaining stories that attracted an audience. It just so happened that men were more interested in the comic medium than women. Luckily, comics can be just as versatile in content as a movie or book, but superheroes were chosen over fantasy, sci-fi, or drama. There's no reason why the industry can't bolster its core audience while also attracting a new one. Unfortunately, it seems like they'd rather ditch one for the other.
