>Incorporating Volcanion(probably resulting in exploring the one place on route 13), Hoopa, and Eternal Flower Floette(more than it already is).
>Z-Moves would be in this game since they were already one small step from the super appeals in ORAS contests.
>More megas for Gen 6 pokemon, as well as some others such as Flygon(writer's block) and Froslass/Slowking(to follow up split evos like Gallade in ORAS).
>Probably something akin to the megalith story from the anime, but more like you storming Team Flare's base(Team Flare fucks up the environment in the process somehow so Zygarde can come out of Terminus Cave and stop them).
>You don't actually catch Zygarde until you go back to Terminus Cave after beating Team Flare like in Gold and Silver or Pokemon Generations. Naturally, Zygarde Complete works more traditionally as a form change.
>Project AZOTH either incorporated into Team Flare's "everyone but us has to go" plot or is the substance of the postgame(alchemy theme might even tie into some SM themes like the alchemy references of Solgaleo as the lion who eats the sun and the stage 1 starters, especially Litten, resembling alchemy symbols).
>Greater use of undeveloped features like when the rivals travel alongside you through Santalune forest.
>Maybe some more NPC interactions so characters like the Gym Leaders and E4 members feel more fleshed out, as well as giving more of them Mega Evolutions and reworking some of the puzzles.
>Add more pokemon to the already ginormous regional dex.
>Expand certain locations like Route 1, Aquacorde town, and Zubat cave.
>Possibly different set of second starters who get mega evolutions, as well as replacing legendary birds with another trio like swords of justice or genies and mewtwo with genesect.
>Various minor tweaks to facilities like hotels and the battle maison+chateau, as well as pokemon lists for friend safaris.
>Make the rivals more interesting by either adding more interactions or tweaking existing ones.
