Hi again!
I requested a new region for the sole purpose of playing with my special pokemons and my creatively assembled team for a bit longer, thats all. If you do not feel like doing it then don't do it. May be, after you have wrapped up with the current altered typings and all the other stuff that are in your mind, think about it one more time. An extended region will increase the playthrough time and excitement if you have strong reason to explore the new region. 😇
Now then, I have done some research on this altered typings and I would like to discuss it in detail. Please bear with me. Firstly, lets talk about the ways you can alter a pokemon.
1. You can alter a pokemon wholesale. For example, you change Fire/Flying Charizard into Fire/Dragon. In this way the original poke is gone. I will not recommend this way as some people are religious to original typings.
2. You alter the final evo of a line. For example, Charmander to Charmaleon and then Charizard to altered Charizard. In this way if you have two Charmanders then you can have your canon Charizard and the altered Charizard as well. I will recommend this way, its time saving and convenient.
3. You change the whole line from scratch. Its very tedious and I think its beyond the scope of this hack.
I have also come up with a name for the altered pokes of this hack. Its Morphed pokes or simply Charizard-m. I hope you like it. 😊
Now, there are certain ways with which you can mess with a pokemon. It totally depends on how much you can expand your skills and abilities.
a. type altering
b. BST altering
c. movepool altering
d. abilities altering
Lets talk about the ways to obtain the Morphed pokemons. The ways I can come up with are Stone Evolution (evolving a normal Charizard into Charizard-m by a particular stone or Morph Stone), Trade offs, Gifts, hidden grottos or a certain NPC which converts normal pokes into morphed pokes. It would be great if you get these special pokes by certain ritual or with certain event (You can expand on it).
I have certain wonderful typings on my mind if you would kindly consider them. The final call is yours obviously.

You can also consider some modern features if possible atm, like

IV display
Hidden ability pokemons etc.
Good luck and all the best. 😄
