I feel like that version of Impa may not be taken too seriously and would not really fit the style of the other Zelda characters. I know Ocarina of Time could be seen to be over represented and that version of Impa could be seen to be more of a Sheik clone, but I still feel that it is one of the better designs of the character.
I mean she just looks like she is ready to get down to business
and defeat the Huns...
That's exactly why I think she's not a good option. Impa is capable of tons of stuff, instead of being a clone. This one is a decent design, but isn't really unique.
Diddy Kong is gonna implode somewhere but I kind of agree.
Impa is the only naturally reoccurring face in that franchise, she's not of utmost importance that she can't sit out, but she's more relevant to the franchise than someone who is more recognizable like Skull Kid.
But I'd love Impa if she happened.
I just want Zelda to get more love and a new character, but I feel like it needs that face that blows up so much that Nintendo starts making Zeldas that just don't even remove him or her.
And legit I have no clue how you'd even include someone like that into the franchise. Not even making Link an avatar as a lot of people throw around on the internet would do it, because if female Link became a thing she'd just be interchangeable like all other avatar characters in Smash.
Heh.
But yeah, Linkle, as neat as she would be, might not work well when they've got a bigger character in Lana/Cia, the stars of the game. Then you got the factor of "why can't she be an easy alt with slight changes?" issue, which is also bad because LInk is supposed to be Male in canon. That was put to rest, as a part of how the Triforce chose its users. I don't like it, but that's what it is.
Finally, she has enough potential to be a semi-clone or more.
The thing about Impa is again, her inconsistent designs. She's either slim or elderly. However, what keeps the Oracle designs from being an issue is, despite being larger, she actually looks quite capable of fighting in multiple ways, while avoiding the clone issue. She could still be fast to a degree(look at Wario), but could show off her immense strength she's possessed lately. This doesn't eliminate weapon or magic choices either. Now, it's true she didn't actually fight in this form. But that shouldn't matter. What matters is representing the character well. This one is very easy to translate to the newer Smash games due to a simplistic design, and to be frank, I want to see more heavyset/older women playable in fighting games.
Anyway, due to being the most recurring, and less controversial than Tingle(another great choice), I feel she could finally get in. The fact she finally got Trophies in Smash helps. As much as I'd like Pig Ganon, I wouldn't be surprised if he's omitted for one reason or another(like Ganondorf's Final Smash representing him well enough, not interested in more villains, etc.)
was a semi-clone of 
)" etc, while true ones, to my knowledge, have always claimed specifics, where possible. It just seems like an easy fallback maneuver.
