This is the reason why I would love to have Dixie & Kiddy as a team.
Dixie & Kiddy would be like semi-clones of Diddy and Donkey (speed, strength, weight, A moves) but as a team with their unique sets of special moves. IMO, it would be the closest thing we have to a Donkey & Diddy team in Smash without compromising Donkey or Diddy's movesets/playstyles.
Dixie's special moves
B - Feather Bow (shoots feathers like Link's B)
Side B - Kong Smash (Dixie throws Kiddy like throwing Bonsly)
Up B - Helicopter Twirl (propels up with her hair like Link's Up B but then she starts floating down like Peach's Up B)
Down B - Kong Tag (switch to Kiddy)
Final Smash - Ellie (the Kongs ride on the elephant as it squirts a powerful jet stream of water, pushing enemies off the stage)
Kiddy's special moves
B - Giant Punch (same as Donkey Kong's B)
Side B - Kong Roll (Kiddy rolls around like Yoshi's Side B with Dixie balancing atop Kiddy)
Up B - Kong Throw (throws Dixie up like Ice Climbers' Up B)
Down B - Kong Tag (switch to Dixie)
Final Smash - Ellie (the Kongs ride on the elephant as it squirts a powerful jet stream of water, pushing enemies off the stage)
