Got bored, and looked up Dixie's page on Mariowiki for some inspiration.
Dixie Kong B moveset:
VB Hair-copter: On the ground it works similar to Ice Climber’s spin attack, only lasts a little longer, and moves quicker. It is however, slightly weaker as well. In air the move is a useful gliding tool.
>B Wild moves Dixie jets forward, propelled by her barrel she rides in DK Barrel Blast. The attack is similar in some respects to Falco/Fox ^B, but slightly weaker, and faster acting.
^B Barrel Blast: A barrel appears and launches Dixie upwards. While being launched she can do major damage to the opponent, but on her fall back down, she is vunerable
B Barrel throw: Dixie puts her long blonde ponytail to work, and throws a barrel forward. Depending on how long you charge B, you could get a wooden barrel (Just rolls normally) a metal barrel (Bounces, but moves slower), or a TNT Barrel (Explodes when it comes in contact with something/someone, but moves the slowest)
Notice how her fur kind of looks like a suit? We know Diddy and Dk looked like this for some time as well, so I guess we can assume she didn't make to the "brawlification" stage. She was never prettied up and whatnot.
ALSO, I noticed THIS on K. Rool's Melee trophy:
The demented head of the Kremlings and big boss in the Donkey Kong series. K. Rool is a giant, greedy glutton with a serious eye tic. While he fits the evil boss mold nicely, he's just enough of a bumbler to have gained a few fans over the years. His plan to blow up the DK Isles with his Blast-o-Matic shows how unbalanced he is
Goroh, Melee
A rival bounty hunter, Samurai Goroh has crossed paths with Captain Falcon in many a dark corner of the universe. He also goes head-to-head with Falcon in F-Zero races, so the threads of their fates seem to be deeply intertwined. Samurai Goroh is famous for his katana, and his signature T-shirt is instantly recognizable.
Meowth, Melee
This... is Meowth's dream. Meowth strides all over the globe, scattering invitations to other Pokémon insisting they come to "Meowth's Party." At this wonderful party, guests are packed in like sardines as Meowth climbs up the stage with its faithful guitar. It strikes a chord, pauses, and then rocks their world!
Maybe Sakurai didn't get the Memo that this game was a no go?... lol
