People keep talking about if Gamefreak will or won't make pokemon more focused on doubles, but how would that ACTUALLY look like? What'd pokemon have to change to refocus itself on doubles?

Here's some of my ideas:
>You get 2 starters. One is from a classic Fire/Ground/Water trio and the second from some other triangle (like Bug/Poison/Psychic for example)
>Two front slots, 4 back slots, TWO following pokemon
>Most wild encounters are 2 to 5 pokemon, if it's a modern game 2 to 5 join in to fight you.
>Many more trainer "duos" introduced, besides the couple and twins we have, with some wacky ones too
>Parent and child, grandpa and grandma, doctor and patient, policeman and criminal
>If it's a modern game, the gimmick would be about the "bond" between your pokemon and give some kind of buff to both as long as they're still out
>new moves introduced are moves that have a "chance" to hit both opponents
>more double battle related abilities, and the ones that already are in the games now have a purpose

That's all I can think up. And I really don't care if GF will or won't do it, this thread is just to speculate how such a game would be like.
