i want suggest if its possible before to defeat the elite 4 in each region, have a battle tournament similar to the animes. for example: in the anime ash has 4 battles before to loose XD (excepting in the orange island). my suggestion is, like PRO is a combination of anime-games, before to beat the elite 4, have a mini battle similar to the ash battle with 4 pokemon trainer one by one. and if we are the better we can battle with the elite 4.

 

i suggest 3 battle with 3 trainers, similar to this:

-before to battle with the elite 4 kanto:

trainer 1: TRAINER 1

trainer 2: GREEN

trainer 3: ASH KETCHUM

 

-before to battle with the elite 4 johto:

trainer 1: CRYSTAL

trainer 2: SILVER

trainer 3: GOLD

 

-before to battle with the elite 4 hoenn:

trainer 1: MAY

trainer 2: BLASCO

trainer 3: RUBY (THE TRAINER WHO DEFEAT THE TEAM MAQUA 3 YEARS BEFORE OF THE HISTORY)

Not sure about this. I think that the Elite 4 are challenging enough already. I don't think there needs to be more of a challenge; especially for newer players :P

With this way we can see some npc that we meet at the begin (ash and may ) that came to be in the pokemon league, and with megaevolutions, for example ash ketchum could have megacharizard y, because red has megacharizard x, and green mega venusaur, but the levels would be, to the first battle 70, to the second battle 80, to the third battle 90.

 

Also, in the anime, the pokemon league and the elite 4 in each region is not the same, beating in the league pokemon is a competence between all the trainers that have the eight badges of the region, but battle with the elite 4 is a battle that is only to the best trainer, not available to all trainer that have 8 badges (in the anime )

 

This suggerence is to try to make a difference with the other pokemon games, and to be similar to the anime events

Red could have to megacharizard x in all his battle, and ash ketchum could have to megacharizard y in all his battle.

The red team would be :

Megacharizard x, blastoise, venusaur, espeon, snorlax, pikachu.

Rhe ash team could be :

Pikachu, butterfree, pidgeot, blastoise, venusaur, megacharizard y
