That would actually be awesome!
Btw everyone remember that guilds and guild members are like the superhero version of this world, so kids idolize your characters. The longer you've been in a guild, the more famous you are. Children don't care about the ranking system, they just look up to whoever they like while teenagers and adults do focus more on the rank.
So feel free to have some children run up to your characters and interact with them. Even if you're new, the fact your character is in a guild is more then enough for them.
Also, no adopting them. (I'm looking at you Emo)
Oh and they LOVE Pokemon, but as expected they don't know how to treat them well. The kids are from newborns to 10 years old.
