There are no reasons for them to join Fairy Tail. Gajeel joins FT because he's a Dragon Slayer, same for Wendy, which has a bigass role. Again, FT has already had an enormous character roster already, adding more would be pointless. Also I doubt her could join when the island is surrounded by the Council ships, pretty much like Jellal and Hoteye in the OS arc.
