From another thread on the same topic: Matako wrote:

Peach possesses exclusive and individual abilities. Daisy is the ruler of Sarasland and has no political power in the Mushroom Kingdom, so she couldn't use a Toad like Peach. Then there's Peach's ability to use her umbrella to glide through the air as well as her ability to float, which are individual abilities exclusive to Peach Daisy does not possess. The turnip throw is also an ability used by the heroes of Super Mario Bros 2, a game Daisy wasn't part of. Then there are the attacks including the hearts, which would fit neither Daisy's color theme nor her personality and the final Smash which wouldn't make sense if Daisy used it, as the Peaches summoned during that attack are a reference to Peach's name. The sole close combat skills would fit, however.

With the Koopalings, technically speaking, the actual fighter is the Junior Clown Car; Bowser Jr./the Koopalings are just piloting it. Being related (blood relation is in question, although they are all still Bowser's underlings), it wouldn't be surprising for them to utilize their own version of the Clown Car to strengthen Bowser's army. With the Final Smash, yes none of them have Jr.'s paint ability; however, you can't expect for the FS to be different for each one of them. Adding separate Final Smashes for these 7 alts just means they would have to turn into 7 unnecessary clones, with their own separate slot, making the Mario series take up more space on the roster. It's just one tiny bit of non-canon. exactly, that's why I think that if people really want to play as Daisy that much which they probably don't tbh then she should be put in Peach's slot.
