I updated it for Gen 7. The only pokemon that aren't available in HGSS are Glaceon (which should've evolved in ice cave anyways) and Alola forms, which I thought provided some cool opportunities for these trainers. I'm sure at one point they would've gone on vacation or ran into a tourist from alola who was willing to trade.
Everything is moved up to BW2 Challenge Mode's level curve, which requires moving some stuff around. Wild Levels, which are notoriously bad in johto, are boosted to provide decent grinding locations. Slowpoke Well now has to take place after Bugsy to raise the Rocket levels and provide more exp before Whitney. Chuck->Jasmine->Pryce has to be an enforced order so keep wild levels at a decent place. An event needs to be added between Chuck and Jasmine for leveling (Drayano's SacredGold/StormSilver added a rocket takeover of the safari zone which would work perfectly here). Radio Tower Takeover now needs to take place right after the player raids the base in Mahagony town to provide levels for Pryce.
This was a lot of fun to do.
