I agree and disagree with you. Pokemon is sort of outdated. The battle system maybe complicated when you get into IVs, EVs, and other competetive stuff, but absolutely none of that needs to be used in the actual game. Do you need a perfect IV and EV trained pokemon to beat the champion? No! I almost soloed the entire Elite Four of Black thanks to a Scrafty I'd been using since the desert route.
The only problem with what you want for the battle system is that, while it doesn't seem complicated, it will be. For example, What if a little kid is using his Gallade against a Hitmonlee? His Gallade uses Psycho cut, Hitmonlee uses High Jump kick to dodge it and attack. The kid goes WTH?! and tries it again. Fails again due to HJK. The kid trys Nightslash, same result. Leaf Blade, same. Hitmonlee is essentially able to win against Gallade because the Gallade only has physical moves, and no "block" moves that can stop it.
And I can tell you understand this is a kid's game series. I can also tell that you're trying not to make this too complicated. I hate to say this, but you're not doing the best job. Do you understand why we don't need EVs and IVs in the main game? Because the NPCs don't take advantage of them, either. I'm not entirely sure, but I'm pretty sure all NPC's pokemons have 1 IVs in each category, and no EVs. This means our Pokemon have an automatic advantage, even if they had terrible IVs and EVs. This system is also subtle enough that little kids have nothing to worry about when going into battle. If they did implement your system, it would have to see little use in the main game and more use in competetive, due to its complication. And, by extension, they wouldn't put nearly as much effort into it since the features couldn't be advertised without younger pokemons going "Whaaaaaa... How does that work?"
Although, quite honestly, turn based RPGs in these days are all pretty stale. Come on, is there really much difference between "Snivy, use tackle!" and "Cloud used Omnislash!" except for the end result. None of them ever bring anything substantial to the table. And don't say "Customization" or "Awesome Story". I mean battle mechanics. "Oh, there's a gauge that let's you do a super attack!" "There's multiple battles going on in multiple places at once!" "You can attack from the ground or fly into the air!" I really don't consider these to be too awesome. Your ideas I actually find pretty interesting.
All in all, your ideas on the battle system could and probably would work, just not in the Pokemon franchise. If you found a programmer and sprite artist crazy enough to take on your challenge and make a game like Pokemon with all that you'd probably be rich.
