I’m afraid I’m not familiar with that series. It’s sort of fine in theory, but official sources are always very cagey with how Pokémon experience the inside of a Pokéball. The image below, with Iris’ Dragonite, is the closest thing I’m aware of to an actual depiction of what it’s like (though note that, if it looks grumpy, that’s not necessarily because of conditions inside the Pokéball – “grumpy” is this particular Dragonite’s baseline). I think originally Pokéballs were imagined to store Pokémon as data in a similar way to the PC network, but then the anime did things that made it clear they were still aware while inside, and could leave at will. Probably several people at Game Freak have thought something along the lines of what you’re talking about at one time or another, but I’m not sure anyone has ever gone through to see whether it’s consistent with how Pokéballs are portrayed and how they work throughout the series.
