The problem with that is that, in the end, you are carrying a multirotor on your plane. It is not so efficient as a fix-wing or plane and it does not perform like a multirotor, because it lacks hovering endurance. That convertible concept does make sense for some specific applications, but they are not the perfect-for-all solution either.
