It pretty much is already. With applications like JKSV already there, all that'd really be the defining problem is updating the applications that let users gen their Pokémon like PkHex.

Heck, you could use some applications from 3DS Homebrew to make it so that you could have Galarian forms before you even have a copy of the game, assuming the basic structure of the Pokémon and their forms are handled the same way as in past generations.


I'm not gonna say to go out of your way to do it (unless it's something you wanna keep to yourself, then by all means, I understand) but as it stands, it's pretty easy based on existing tools and apps.

 

I was mostly referring to using older games form data. Hence why I never said anything about outright new Pokémon and only mentioned the forms.

When I was bored a while back I tinkered around with shifting forms of Pokémon that normally can't on the 3DS games.
I set a Geodude I had in Omega Ruby to have its form data altered and it showed up as an Alolan Geodude in Moon.

But as I said earlier, that's an assumption based on if things are kept to be similar to how they have been before.

It's purely hypothetical, though I should've flat-out stated that earlier.

 

Who are they?

 

pkhex works on let's go already so pretty sure gen 8 will be implimented
