It's a logical configuration, and one that more people would be wise to consider. Everyone wants to do something fancy and weird in the hopes of some imagined benefit, but this concept gets the job done, and if you dig into the analysis it has some considerable advantages.

The only problem with this configuration is that it does not readily scale to a full size plane. But perhaps it could be viable in an octarotor arrangement, considering also that in the case of one lift engine failure it could still land conventionally, though perhaps not at its intended destination.
