1.Change starters to hoenn starters instead of johto....and make johto starters avalible later in the game.Blakizen,sceptile and marshtomp are the best pokemons as starters even better than gen 6 ...they even have megas so when megas will be added their mega stone could be provided later in the game....
2.make more legendries avalibe in johto only because number of legendries are very less....u can add articuno/moltres/zapdos ....which after having defted 8th gym are either avalible near victory road or have a 1/50 chance to appear any where in wild.legendries are so less.
3.Add 2 different evil groups in game which shall effect game play a lot based on disisions.
4.when megas will be added add some unique megas too ...i have given a few suggestions earlier.....your choice wheather to consider any of them or not( http://pokemon3d.net/forum/threads/9767/ )
5.add good animations for moves......
