You could make the game run on Battle Tower rules where level is irrelevant in actual battles to maintain difficulty, but that wouldn't change the fact that visiting an early route in another region would still have you pitting a fully evolved Pokémon with a good moveset against early game Pokémon. It would have to be a game that functions like the anime, where your character drops his party in storage every time he starts a new region, but has optional access to it if you want to steamroll early trainers. There wouldn't really be a story beyond collecting badges and beating each regional League to reach the national League, kinda like what the beta GS ROM seemed to imply, though they scaled all of Japan to about the size of one region.
Play solo and start in the city you want, though it'll determine where you go next. If you start in Kyushu, you better be prepared to wait a long time to reach Hokkaido, but you could go to Chugoku or Shikoku next. Comparatively, you could start in Chubu, and your next regions could be Kansai, Kanto, or Tohoku, while starting in Hokkaido would mean you have to do Tohoku next no matter what.

You'd have to make a new Kanto that more accurately fits real Kanto and separate the Chubu part from it. Tokyo would be the location of the national League and would be the biggest hub in the game.
