Yea it would be, but I doubt anything in it could be changed to one. Might try to see if there's a way to do so, but they'd have to change a stop to a Gym.
There isn't just yet... given that it's only in some countries at this point (Arceus knows when it'll be released in the US). Only way that I know of is to play Ingress and get up to a certain level. Not interested in doing that -- both in regards to playing and due to my phone already being low on space as it is.
Wow that's a lot of Meltan!
Probably.

Woo-hoo! Latias and Latios are a part of next month's research rewards!

Also some new Pokemon are available in eggs.
Just hoping my 10km egg luck improves!
