The only problem with this is you have to delete some of the pokemon that are in the game. So say you want the starley line but not the pidgey line you would take it out and put in the starly line. There are like 2 or 3 tools you will need look up advance pokemon sprite editor which will let you change the sprie and YAPE (Yet Another Pokemon Editor) will let you change the name stats and type stuff like that as well as the moves. If you have anymore questions you can just PM me :)
