...Not sure what you tried to prove here? I mean she has a different hairstyle, and she is a tiny bit shorter, but ok? I mean, technically Wii fit trainer Female was shorter than her male counterpart, but they were adjusted to be the same height. Heck, the koopalings are totally different, and they still managed to work. Even Daisy looked a tiny bit noticeably different from peach, they could still make her hurtboxes/hitboxes exactly the same.
Don't get me wrong, I think a majority of people think she would probably have a sports moveset if not a clone...but thats also a problem. Do people really care about sports all that much here? Like would it be interesting? Sure, it's unique, but do people care about it?
I think the overall problem with Daisy is that she doesn't have anything really going for her.
Rosalina beat her out in terms of character with her whole backstory business. Waluigi beats her out in terms of hilarity. What does Daisy have? She's a tomboy? A whole bunch of other characters in gaming are as well.
The only main series game she appeared in was Mario Land, which she didn't do anything in other than exist. Even then, the only reason she did was to help build the brand new world Mario was in...which hasn't been brought back since. Characters like Rosalina were at least more involved in the plot.
Overall, why would people who don't care about Daisy, want her? Thats the main problem I feel. I mean sure, I'm a tiny bit hypocritical when I say that involving Bandana Dee who is in a similar boat, but at least people want a new Kirby character and/or could be interested in the idea of a spear based moveset. And thats another thing, Daisy is in a majorly populated series.
Daisy has everything against her I'm sorry to say.
