Well this changes everything! Sort of

If you're concerned about keeping it limited, you can probably just limit is to whatever's canonically found in Kanto way back in gen 2 plus or minus a few of your choosing. Throw in the occasional Johto native when we're battling an NPC, stuff like that. I mean if I remember correctly like Slugma and Skarmory were originally only found in Kanto? I get what you're trying to do so those are just some suggestions and reminders. Pokemon distribution is bendy so you have quite a few options
