Fediverse idea: FediMiiverse

I see people talk about fediverse alternatives to the big names, but the social network I want to see have a fediverse equivalent the most would be nintendo wii u's Miiverse! Miiverse was a strange social network, where you could post images, chat, and even create doodles in. Instead of likes, or dislikes, there was "yeahs". Did not last past the wii u. While there have been miiverse alternatives in the years since, none of them quite caught traction, perhaps maybe a federated version could fix that?
