Finished the current content and it's honestly pretty great! Some bugs, suggestions and questions below.

Something I was thinking about was making legendary raid-esque boss fights, you fight against a legendary with highly increased HP and empowered moves with 3 of your pokemon out at a time, trying to chip away at it while carefully managing your own team. Of course, certain moves like Perish Song would have no effect, and status effects would automatically be healed every few turns, so you need to keep reapplying them. Also, field moves from Pokemon Ranger, they allow you to access hidden areas/shortcuts provided you have a pokemon with a suitable move in your team. Finally, if a level cap is implemented, allow you to store excess experience so it isn't wasted.

I was thinking about something similar the other day, except they would be "tactics", basically certain styles of battling /strategies /battle cries that can be used a limited amount of times to give an advantage; these would be classified on levels depending on how strong they are, and you would need to spend a certain amount of "points" to use them (higher level=more powerful=more expensive), these points would be limited per battle, so you can either use several weak "tactics" or spend all of your points in a few, very strong ones. Effects would basically include stat boosts, reducing/increasing damage of certain types/categories, certain status move effects (taunt, defog, protect, etc) and maybe even allow you to summon a certain Field Effect during a limited amount of turns. The player would start with only the most basic ones and then acquire more of them as they defeat the trainers who use them (in the sense that you're learning and assimilating their styles into yours).

Personally I think your team is pretty okay to deal with Emily: Graveler and Krookodile should be able to deal with Electivire, Jolteon and Manectric, Sceptile with Rotom, Magmar with Galvantula and Machamp with Eelektross. Try to defeat Galvantula without giving it a chance to set up Sticky Web, Eelektross has an Assault Vest so it's better to use physical attacks against it. Completing the Addenfall ranger quests can be helpful since you can get a Choice Band for Krokodile/Graveler, also if Greninja is not being very helpful consider temporarily replacing it for something that can at least be useful (you can catch a Froslass at lv45 with Destiny Bond in the silver forest for example). As for your team in general I would recommend replacing either Graveler or Krookodile with a Poison type since it helps to deal against Fighting and Fairy types.

I personally had more trouble against his Staraptor and Heliolisk since I didn't have good counters against them in my team. Lopunny was easy since I had an Aggron with Protect, so I just baited High Jump Kick and had it kill itself with the recoil damage. Shinx can be found in the woods North-West of Addenfall (where you fight Amelia for the first time).

Oh OK, just wanted to make sure I didn't miss it or anything.

You can obtain Aron in the Weeping Hills, interact with one of the broken tombstones to open up a cave where you'll find it. On another note, has anyone completed the sidequest where a man from Blackview asks you to find a doll in Bronze Island?
