I have done a quick mock-up of the design just now too, using the above images.So both of these images come from Boeing filed patents, not to mention, they have given many renderings of this specific aircraft on atleast 5 separate occasions (patents include) all of which show top mounted intakes. In the one that speaks to deployable canards above the intakes, it makes specific mention of pressurized air ports to aide in keeping air flow to the intakes during low speed operations.
a major problem with the design is that it doesn't have the space to hold a radar in it's nose, and even is not depicted with one as we see cross sectional cut-outs of the aircraft in some Boeing marketing material.
