FFII: Maria and Leon. Leon is the next best villain that represents FFII, besides the Emperor. As for Maria, she'd make the story interesting, since she'd be fighting on the opposite side of her brother, except unlike Cecil and Golbez's sibling conflict, Leon would probably be too overcome with power to listen to her sister's pleas.
FFIII: Blue Onion Knight? They can't really add Luneth since Red Onion Knight and Luneth together would be a bit of a paradox. Maybe Desh actually, since I can't think of any other reasonable choice. For villains, Zande, definitely. He'd really contribute well to the story with his "what good is there being human?" personality.
FFIV: Rosa (Cosmos) and Kain (Chaos). I can't think of any better combination that would enhance the story better, especially considering they'll be alongside Cecil and Golbez, respectively. Nomura was also really wanting Kain to be in, even to the point of replacing Golbez with Kain (I'm insanely glad they didn't though). I hope the Kain fanboyism won't get too out of hand if it does happen...
FFV: Gilgamesh, definitely. He'll help add to the number of "good" bad guys on Chaos' team, and his personality is much different than anyone else's in Dissidia (except for maybe Bartz's and Zidane's). As for good guys, either Lenna or Krile since they've lost quite a lot in FFV. Come to think of it, so did Faris. I guess any one of the playable characters would work.
FFVI: Though Nomura wanted Locke in, I'm kind of thinking Celes might work better, especially since the new villain for FFVI would probably be Geshtal. Celes and Geshtal would probably be a better hero-villain pair than Locke and Geeshtal. Though Locke would contribute to the story quite nicely with his personality of never forgiving himself when his friends come to harm.
FFVII: Rufus, Reno, Hojo, or Tseng would probably fit the best for Chaos. As for Cosmos' side, maybe Tifa (since she's Cloud's childhood friend and she knows Sephiroth quite well) or Aeris (she'd make a good hero villain pair if Hojo or Tseng is the new villain). I'm hoping the Tifa fanboyism also won't get out of hand, or at least the fanboyism for her, you know.
FFVIII: Rinoa and Seifer, since Square Enix said they were considering putting in Seifer, but then Rinoa would have to be the hero represented in FFVIII, or was that for FFX? Either way, I think it works.
FFIX: Garnet, since FFIX's story revolves around her mostly. As for villains, I don't know FFIX well enough to make that call. Maybe Garland, but having two Garlands is, a bit weird.
FFX: Yuna and Seymour, since Square Enix said they were considering putting in Seymour, but then Yuna would have to be the hero represented in FFX.
Wishful thinking:
(note: joke character suggestions are highlighted in yellow)
FFI: Thief/Ninja and Astos.
FFII: "What's Mythril? Is it yummy?" kid/Mindu (always found him cool) and Leon.
FFIII: Four Old Men and Zande.
FFIV: Yang and Rubicant.
FFV: Lenna (I hope they use the sprite hairstyle with pink hair rather than Amano's artwork or otherwise she'd be a Terra clone) and Gilgamesh.
FFVI: Edgar/Cyan (it'd be cool seeing tools/swordtechs being used in Dissidia, especially Chainsaw/Quadra Slam) and Geshtal.
FFVII: Vincent (maybe he could partly morph so his hands turn into claws for melee attacks) and Palmer (and the dreaded butt slap)
FFVIII: Rinoa and Seifer.
FFIX: Vivi and Queen Brahne.
FFX: Auron and Seymour.
