Maybe you will listen my ideas (you haven't to use it if you don't like)
I watched "Charmander the stray Pokemon". It is said that they were at Route 24, therefore you should remap these series. And Bill's Lighthous should be at Route 25.
Make Meowth with Team Rocket (I don's see it in Viridan Forest, 4 example)
And make Misty and Brock your rivals.
And a question: Will you make Johto?
