Unless you're Batman or Superman, it's pretty hard to have two books on your own and at some points even Superman struggled to keep both. GL doesnt really count because all GL books are different with different protagonists. I dont know if Hal himself could hold two books. Maybe he has already but if i'm not mistaken GLC always had the other lanterns with him.
So my suggestion is that unless WW somehow becomes hugely popular, it's going to be hard for her to keep two books that just tell stories about her. It's better not to risk too much and lose it all. So the second book has to be a bit different in a way. You could make it more superheroic (Cheetah, Giganta and all that) and keep the main book the one with the Vertigo feel but i dont know if that's good enough.
So i have three suggestions:
1) Wonder Woman based event that affects the whole universe. Why should we get events like that only based on Batman, Superman and GL? The second book will come out of the event the way Red Lanterns spawned out of the Blackest Night. It would be about WW and whatever plot or characters are left after the event.
2) Action Comics type of book. Handles her origin and early adventures around the world. What would you do if you suddenly came to a new world full of wonders? Sit in one american city and get a job or explore?.... Exactly. So we could have an 18 year old WW travel around the world and meet various people and cultures, try new things, and mature into the WW we know now. Fighting english folklore monsters and searching for King Arthur's tomb
(a), going all Lara Croft in the pyramids in Egypt, walking around the markets of Cairo, and finding "the secret of
Alexandria's lighthouse"
(b), following the tracks of Alexander the Great across the Middle East all the way to India and meeting some maharajah with 100 wifes (there's your usual sexual politics)
(c), getting lost in the maze that was Hong Kong's Kowloon walled city (demolished now but lets pretend it wasnt in the DCU. Nolan based his Narrows on it)
(d), getting accustomed to 21st century technology in Tokyo by teaming up with a dorky kid who likes videogames (the new Toyman perhaps?)
(e), etc.
3) B&R style book with the dynamic duo being Diana and Steve. Since Johns broke them up, i guess this has to take place in the past. This could also be part of (2), in other words Trevor could join her in some of her adventures.
