Pac-Man's a virtual lock, but I could see Lloyd being a second Namco rep. I mean, Tales of Symphonia was the GameCube's main third-party game... that wasn't named "Resident Evil 4," anyway. The influence it had on the Nintendo community was huge; so, Nintendo would probably be eager to get Lloyd in Smash.
Really though, Namco's involvement here opens up several other awesome possibilities. We could even see someone truly crazy, like Mr. Driller or Mappy; the former's been surprisingly prolific over the past decade or so, and Japanese audiences go apes*** for the latter. Personally, I'd love to see Dr. Don and Dr. Dan from Point Blank, but I know that won't happen. >_>
Oh hey, I just remembered Klonoa. He could make it too.
