only if you put them all on the same island. If you, say, put fire and water boosts on one island, earth and plant boosts on another island, air and cold boosts on another island and metal and lightning boosts on a fourth island, then you can double up the boost power for many hybrid dragons. (i.e. if you put a salamander or panlong dragon on the water/fire boost island, then you will have double boosts for those dragons). I have a blog that somewhat explains this concept, although it is out of date as I haven't been on here much lately.
