1. Paula (More magic users are always good, her abilities are different from Ness' and Lucas', so she would be unique)
2. Jeff (He, unlike the other EB characters, doesn't have PSI, but instead has a range of inventions that could be used to create a great moveset)
3. Poo (He could work as a cross between a straight up brawler like Little Mac and a PSI user like Ness. There's a lot of potential there)
4. Louie (HE WAS THE KING OF MONSTERS IN PIKMIN 2. Unlike Olimar's use of Pikmin, have Louie use the beasts from the game! There is so much that could be done with him!)
5. Chibi-Robo (This is extremely unlikely since Zip-Lash is a massive flop and an affront to his incredible roots, but there is a lot they could do with him)
6. Captain Toad (His game has actually sold surprisingly well, his lack of jumping ability could be made up for by his dexterity and strength)
7. Quagsire (No, I'm not joking. His moveset in the Pokemon games is vastly different to those fighters already available and just look at him! He's very marketable!)
8. King K. Rool (He would likely end up being a clone of Dedede/DK/Bowser, but if they gave him some moves that utilised the Kremlings, I would be very happy.)
9. Phoenix Wright (He's practically a Nintendo character, and he's been in a fighter before, so there's a moveset already!)
10. Dixie Kong
