Ghirahim brings to the table a type of character we don't have: a flamboyant showboater. (Well... we do have Sonic. Still, two is never too many.) He doesn't even need to taunt... I'm sure idle animations alone would get the point across.
Only Sonic? What about Falcon, Groose? "SHOW ME YOUR MOVES!"
Rayman
Chance: 8%
Rayman's undergone a bit of a revival of recent starting with Raving Rabbids on the Wii, one of the launch titles. Good job too, before that he was fading into obscurity. Rabbids unfortunately overtook the lead and soon tried to conquer the world, and began swallowing up Rayman within a game he started. Luckily Rayman origins came along and easily became one of the best platformers of last gen and thus Rayman and his quirky expressions and slightly off the wall sense of humour became more well known and the character more popular than ever before.
Rayman is a well recognised face now, not that he wasn't before, but I can't help but fee Origins gave the character a lot more charm than previous incarnations. By all means Rayman would be an excellent mascot if this was "video game all stars".
But sadly it's not. It's a Nintendo All Stars, and to get in without being a Nintendo character means you have to be of Legendary Status: Sonic, Megaman, Pac-Man. These are legendary characters and unfortunately for the limbless buffoon he doesn't quite match up to his fellow "Man" mascots. At least not yet. He is probably around the same level of fame as Bomberman at this point; recognised, but not a legendary character.
Want: 90%
Honestly, I love Rayman, and after playing Origins you better believe I want this guy. I have yet to play Legends, but just the art style, the expressions, the weirdness, I can't help but love a character like Rayman. I have no idea for what his specials would be, aside from Up+B (his propeller hair), but I'm sure whatever Sakurai could come up with would be amazing.

Dixie Kong
Chance: 80%
Dixie Kong is one of the more recognised DK reps, one of the most recognised female characters of gaming(I know this doesn't mean much, but still it's a fact) and starred in two of the Donkey Kong Country games. She isn't just the sidekick of the sidekick as many people have been seen calling her, she's a genuine All Star protagonist which is something even her detractors can't deny.
Dixie was planned for Brawl, and I honestly see her getting in before King K. Rool. She's more recognised, more memorable(you play as her for 2 out of 3 of the original DK Country games anyone who thinks the boss is going to be remembered more than the character you see on screen for the majority of the game is kidding themselves) and has more chance of getting in, seeing as if worse comes to worse she can be a Wolf style clone. Let us also not forget that we tend to get more heroes than villains, and I can't see that pattern changing.
Not a lock by any means(I've been guessing Diddy would show his face up since 64 and it took the third installment for that to finally happen) but her chances are as good as any potential newcomer.
Want: 90%
If it's a toss up between her and K. Rool, I'll side with her. Partly to be different from the "Ridley, K. Rool, Little Mac, Palutena are lock" crowd, but partly because I don't really have any strong memories of K. Rool and I do of Dixie. I'm not against K. Rool's inclusion, but I feel Dixie fits "All Star" better than K. Rool does. Who knows we might get both?

Ashley: 4%
Sorry Ashley. I know she has moveset potential, more than most other Warioware reps(I may argue for Syrup...) but I can't see her doing well.
