I'm not sure what Corrin and Roy have to do with anything about Geno. Piranha Plant being the joke newcomer doesn't really kill Geno. Hell, previous games have shown that a series can get a base game rep and a DLC rep. Sometimes two, with Roy and Corrin.
I'll give you that they can tool around with Sora to not be exactly how he is in the games. However, that can literally apply to every character in this thread. It's no real boon to Sora's chances. I've seen how Geno and Erdrick can work with these stats. Hell, I bet Crono can work with these stats too if you thought long enough about it. Just because it can work doesn't mean a character will get in.
The entire point of the Pokemon comparison was to kill your Cloud vs. Sora height difference theory. You used Kingdom Hearts as a reference to compare Sora and Cloud's height. You can't say they had to adjust height for Pokemon and then say Sora wouldn't follow this. Cloud towered over Sora, especially in KH1. There is no way they are using that as the only metric for Sora's height. They can do whatever they want with character heights. I doubt Sora will be as large as Cloud, but saying he is smaller than Cloud is not the decisive evidence. It's the standard we expect because he is literally a kid.
Transitioning to Erdrick having to be chibi, not exactly. They can do whatever they want with Erdrick's height. The two images below of male and female Erdrick are official artwork that represent them smaller than the averagely proportioned human. It's not a matter of what design they use, because Erdrick has a lot of drawings of him. Sure they give him more realistically proportioned limbs in modern times, but they can make it to like DQ3 where he was drawn to be cartoonishly small relative to how he's seen nowadays. Really, adult Erdrick has only been characterized as having Goku's face. That's all they'll need to keep for his anatomy design. So if we take these two images as what he could look like, especially if he's in a squatted sword stance like Link or Cloud, he can definitely fit the height stat. Especially if the height stat's max height is determined by face and not hair. That means we can ignore the long spiky hair in our height estimations, too.
In terms of Geno's chances? Yeah, I'm not seeing him as likely. There's just so little going for him this time around. The spirit, the planned mii costume, no literal connection to the word Brave, (unlike Sora's Brave form or Erdrick's class literally being translated to Brave), and relatively small fandom outside of Smash Bros. It sucks for me, but I got over it. Maybe in Smash 6.
Personally, I don't even know if Brave is the Square Enix rep. If we go by Vergeben saying that the Square Enix rep was intended to be the first DLC revealed, then maybe that means our next DLC, who most likely is Brave, is the Square Enix rep. It's up in the air now, though, because we still don't know who to expect and when.
"While I do believe it's
Sora, I would not be surprised if it did turn out to be
Sora, but when i watch Brave modded onto Ike I very much see Sora."
I don't understand this. Do you mean Erdrick for the second Sora?
If you have to ask me, I think it's Erdrick or Sora given their status and how unkillable they are in discussions. At this point, I don't know who it is but damn I hate flipflopping between the two.
