You must also accept that the only way Wonder Woman is going to get more series is if the sales increase. And despite having top quality writing and art, that is not happening now. So by cross-promoting the character in other media, you might bring in new readers.
If WW were to appear in films, an animated tv series and say some videogames, you increase her visibility. Throw in some merchandising and before you know it kids are talking about her and asking their parents about her. Books start to sell.
