Uh, I have experience with VR, a year of experience in Unreal Engine 4, and used to work professional as a game developer, so yes :) You gotta keep in mind this is 2D projections too, not real 3D models, all it is is wrap-around images served rotated around a central camera.
I had 4 years of experience with UE3.5 (admittedly, I have not tried UE4), but it's far from trivial in that environment. Perhaps UE4 makes this process much easier, but I can't see it approaching "trivial."
When I see the words "trivial," I think of a weekend project - not something that would involve tons of man hours.
Shared vocabularies are hard :) My definition of trivial is "I can do it in less than half a day", which I've done this exact thing with before (to be able to navigate our office via our indoors Street View map)
