The thing Game freak forgot about and could build upon

back in the GBA era, Gamefreak created the spinoff series: Mystery Dungeon. The series had only a few games, ending on the 3ds console. Within the course of the series, a concept was created that maybe a future game had referenced. The inclusion of a Primal Pokémon. Most of you know where this is going already. Primal Dialga was the first Pokémon to have a special-evolution like form. It is also the first Pokémon to have a form that cannot be obtained in any way unless by hacking. This idea was sorta brought back, when Omega Ruby and Alpha Sapphire came out. Primal Groudon and Primal Kyogre were given a primal form when holding an item, while Rayquaza was able to mega evolve. This left a sort of weird taste in my mouth. When we have the main three home legends matched up with just Primal Dialga, it just looks odd. Maybe gamefreak could add Primal Dialga, along with Primal Palkia and a Mega Giratina to match what had occurred with omega ruby alpha sapphire. Dialga and Palkia would hold a special item to revert to these forms and have different stats and movesets. Giratina would work the same as rayquaza, needing to have a certain move to Mega Evolve. Don't know if this will even work in the core games, but who knows.
