For the 1st one: I asked Wayforward (Of Shantae and Ducktales Remastered Fame) To Give Me Recommendations on what Class Shantae Should Be, they Recommend making her a Popstar (Source: https://twitter.com/WayForward/status/1389276505063137282),
I also Ask them If They Have had the chance and thoughts on those impressive shantae Miis they said the haven't had the chance to try, but do Condone Making Shantae (They're a Very Popular Indie studio that Retweets Fanart so IDK what I expected).
On a (Un)Related Note: MoonSprout Games, Developer of Bug Fables: The Everlasting Sapling Made Miis Of Team Snakemouth from that game (Source: https://twitter.com/PaperBugDev/status/1387494914557194243)
