Structure the main game as it was in Gen 1 and 2 with next to no narrative, and make side content with more story focus. Things like the Looker Quest in XY or the Delta Episode (never mind the poor execution of that, just think of the concept). There's no reason there couldn't be at least 10 different sidequests in the game with that kind of scope and story.
