GAME FAITHFULNESS DOES NOT MEAN SATOSHI SHOULD BE WRITTEN OUT. He's the anime version of Red.
If I was in charge of the anime, I would make it a lot like the doujinishi I'm currently working on right now. It starts off more or less the same, but Satoshi slowly takes more and more levels of badass during the Kanto saga and eventually becomes a better representation of Red from the games. Yes, that means that:
-Rocket-dan (as an organization) plays a bigger role earlier on and eventually gets disbanded by Satoshi.
-Satoshi wins the Pokemon League and goes on to be challenged by the Elite Four as a test that will truly confirm if he's the strongest.
-Satoshi becomes the champion (Professor Oak being the former undefeated champion, inspired by a beta idea from the RGBY games and reeks of epic plot twist).
After Kanto...
-This also means that there is a three-year time skip and Satoshi goes through a Heroic BSOD during that time period, secluding himself on Mt. Silver, and becomes like Red as depicted in various fanarts when he comes back to his senses. And yes, he would be using that badass theme during his battle with this version's representation of Gold/Hibiki (most likely Kenta).
-Different protagonists are introduced, similar to the games and Special manga, with the future generations following suit.
-The above means that there is aging and better continuity within my universe, as Satoshi won't be stuck being the protagonist that gets developed and then gets a reset in experience every region. He's only the protagonist during the Kanto portions.
-A few relationships become canon, albeit in a way that doesn't make you puke. Yuuki with Haruka would be like Ruby with Sapphire from the manga, for instance.
-Remakes get their own plot. FRLG would be like the Battle Frontier in the anime, only that Satoshi is noticeably more mature (AKA I WILL MAKE HIM MORE GAR), gives up his champion title in favor of becoming a wandering trainer to better himself, and takes up a mentor role to a character based on Leaf (female counterpart to Red in FRLG). The Battle Frontier also takes place on the Sevii Islands.
-The Fame Checker from FRLG make an appearance during the portion that is based on FRLG. Leaf will be like "EEEEEEEH SUGOI IT'S SATOSHI THE FORMER CHAMPION [/fangirl]" and Satoshi will be like, "lawl, new kids and their new technology".
In general...
-It's noticeably more plot-driven and the characters are better developed. This means that the evil teams are handled better by being integrated into the main plot and characters won't have a "herp derp reset" button. ESPECIALLY SATOSHI.
Other differences during the part that is similar to the real anime include: Satoshi wearing red clothes (lol, get it?), Fushigidane evolving into Fushigisou, some of his released Pokemon stay with him, Shigeru has an Eevee as a starter instead of Zenigame, Satoshi being able to switch his party Pokemon using a button on the Pokedex (the feature introduced in the lighthouse episode that was dropped into discontinuity shortly after), Myuutwo doesn't erase his memories in the first movie, Satoshi's nickname is Red because of his FIERY RED PASSION, etc... Most importantly, NO PITY BADGES. Well, except for Takeshi giving him a badge for showing good sportmanship by sparing Iwark from a rather unfair defeat, but I make him earn it later by promising an epic rematch in the future (before Takeshi leaves the group).
My idea is basically this: an adaptation of an adaptation of a game that deviates to become an adaptation of a game. If anyone wants, I can post a rough outline of what I have.

I'd actually watch this.
