In all seriousness, I'd love if she were with Ted Kord. Their friendship pre52 was adorable and I can easily see it as something more. And his new look wouldn't look too out of place if he were to appear in Batgirl...
With the exception of Superman/Wonder Woman, it seems that the editorial just hates superhero-on-superhero romances, and even friendships.
They're mostly technically "pre-Flashpoint continuities", but they aren't part of the pre-Flashpoint main Earth. Aside from the three mentioned above by another posters (Red Rain, Red Son, Kingdom Come), the teaser image also shows Pre-Crisis Earth-2, Earth-3, Earth-4 and Earth-X. There's also an image with 90s version of some characters, like Aquaman and Parallax Hal, which although also technically Pre-Flashpoint DCU will need to be treated as its own Earth here, since it's a different period. Same goes to DC One Million, obviously. There's also Future's End itself too shown there. So, yeah, there's still quite a bit of worlds shown which probably will take the other half of the books.
I would like it to be like this.
Dick: "Babs can I ask you a question....Will you marry...?"
Babs: "Oh Dick, I don't know after all we been through but yes."
Dick: "Oh cool I'll tell Vic you want to marry him, he will be keen."
Babs: "What? I thought you were going to ask me to marry you?
Dick: "Haha nah Babs, I'm dating Jesse and boy she's Quick. We are getting hitched next week."
Pretty much not going to happen but I can dream. Anyway not going to buy it because Babs and Dick just never worked out well ever.
And the groom wore . . . pixie boots . . .
