Meh, I think more likely than Geno.
True. I think it's less likely then a Square-Enix character in general (Black Mage, Slime, Geno, Sora, the last two are pipe dreams) but otherwise I truly would enjoy seeing some more characters get the spotlight alongside their games. Scribblenauts was almost one of the must-get DS titles, No More Heroes is defined as THE M-rated series for the Wii (although I may be wrong), and Shantae is... Shantae. WayForward has some good stuff (Batman: The Brave and the Bold is a cool game for being a licensed) and they do kind of help Nintendo in ways. I feel that they'd still be likelier than Banjo & Kazooie, Conker or the Battletoads.
But there ARE some certain characters from other companies I'd enjoy. If instead of everyone's fantasy 2nd Sonic rep SEGA opted for Amigo from Samba de Amigo, I would be happy. Arthur from Ghosts N' Goblins would be pretty cool too.
Back on topic, does anybody want to see more casual representation? By that, I mean series that expand into Nintedo's more "fun for the entire family" games, during the DS/Wii era. For instance, Nintendog, Miis and Karate Joe would represent that well.
