Why no make a pokemon game where you are a newcomer on the International Police?
Instead the typical Professor, you meet Looker and give him your partner pokemon. You go around the region (or smallest parts of some regions) resolving cases, helping people, rescue pokemon over here and over there. Until you met a dangerous team that want do their selfish stuffand the evil boss is the International Police Boss
Almost like Ranger series but with the traditional system about capture and train pokemon.

Other than the spoiler, I would like that. Hell, S/M could have been reworked to accommodate that. You're a rising star, taking on the Island Challenge, and the UBs begin to attack. Looker and Interpol agents show up and are desperate for help. You seem to have potential so you are named a temporary junior agent. You go out and look for UBs to defeat them in battle while also trying to find out what brought them to Alola. This brings Team Aether and possibly Team Skull into play. It also gives the UBs a better role in the story other than "they're making havoc way over there where you can't see them."
