I'm naming my Cloud amiibo Mallow.
Banjo and Kazooie definitely deserve a spot to represent the Rare N64 era (Diddy's kind of doing double duty now of representing DKC and DK64); the big question is whether Microsoft would also let a Banjo-Kazooie game go up on the eShop (maybe Grunty's Revenge)? Every other character in Smash is in at least one other game on the eShop -- R.O.B. is in Mario Kart DS, Cloud is in Theatrhythm and FF Explorers, Snake is in MGS3 3D , and Japan gets Mother 3 on the Virtual Console next month. I don't think they'd put in a character with no potential for cross-promotion at this point.
