Dragons in people would be stupid. This isn't Naruto where bijuu, powers, eyes and other genetic abilities are traded like it's nothing. Even if the bodies of the dragons would be destroyed and their soul or essence or whatever would be looking for a host, why would they not enter the body of their students (Natsu, Wendy, gajeel)? Makes more sense then entering an old hag or a volcano.
