Sorry, a no go. The XB-70 is conventional three surface design.
It’s greatest design feature though is that it is the first aircraft to be purposely designed to take into account and use the wave rider effect found in super sonic flight.
The YF-12 and SR-71 are the first aircraft to experience the effect, and Kelly Johnson did add some ability to the SR-71 to make use of the effect, but not to fully exploit it.
The XB-70 needed to utilize the effect if it was to achieve the range and speeds required.
