This concept of the two tails has been well proven in Burt Rutan's previous designs such as the "Voyager" and the jet-powered "Global Flyer". These two are the only aircraft to have flown non-stop unrefuelled around the world, passing through some vicious weather, so I would say that Rutan's design is not likely to fail easily. I would hope that this bold project does not fail, but its main difficulty is probably the lack of a suitable rocket. Originally it was meant to fly some version of Space X Falcon, but that fell through, and the existing Pegasus rocket has a perfectly adequate Lockheed Tristar 500 carrier and is rather small for the Stratolaunch plane. Given the success that Space X has had with the retropropulsive return concept for boosters, the market for a medium air launch system simply may not exist anymore, and if Starship/Super Heavy works as advertised, it never will.
