I guess 0 degree means looking at the front of the plane, 180 degrees means looking at the tail.
For subsonic bombers you want rear stealth to be as good or better than frontal stealth, because you need to get deeper behind an opponent's territory, and then slip back into your own air space without being detected. You also want to have better long wave stealth to hide from early warning radars.
0 degree is front. I assume the spike at 30 degrees in some of the design is due to when the long straight front edge of the plane-wing form is perpendicular to the line of sight.
Which is probably why in the first two designs where you have two segments for the front edge you have two smaller spikes instead.

That what-if was almost beaten to death in cjdby for its wishful but impractical stretch of J-20 design.
One thing against it was the lengthened J-20 air intake, less stealthy and efficient than back-mounted intakes.
Another thing pointed out by cjdby members was the big canard inherited from J-20, unlike J-20 which uses canard for maneuverability, a bomber doesn't need it. Members also pointed out the vortex generator of J-20 is unnecessary for a bomber.

The US Air Force B-1 Lancer uses canard.
That was also asked and answered in the cjdby thread. The answer was that the tiny "wings" of B-1 is not a canard in function, but some sort of air flow stabilizing device. I remember I first read it in this forum. My understanding (from posts in SDF) is that a true canard is for maneuverability in the same function as tail planes, it has to be big and movable, the device on B-1 doesn't do the same thing as canard, nor resemble the characters of it.

Whether it's for stabilizing air flow or maneuvering it's still canard in design.
I will leave the definition of what is or is not a canard aside. I don't really care what a thing is called, but more into what they do.
