I was thinking more along the lines of the F-117’s approach - the radar signals are reflected elsewhere instead of back to the source, thus making it “invisible”.
Speaking of the 117... aerodynamically it was impossible for it to fly, too, without the widgetry that constantly adjusted the wings, etc, while in flight.
The F-117 was the first generation of stealth. It was not computationally possible to reasonably assess more complex shapes at the time.
Stealth is as much controlling radar reflections to a known point (and then making sure you don’t present a reflection to radars) as anything else. Planform alignment accomplishes this - The F117 “facets” were all aligned to the same point as much as possible - effective and solving a calculational bottleneck. Subsequent generations (B2) still have planform alignment but the fuselage has more complex shapes and coatings.
This was the B2 CTF back in the day, the central courtyard was designed to “sort of” mimic the B2 shape - knowing full well the Soviets would be spending a lot of satellite time focusing on this facility. Someone had a sense of humor by doing this - figuring they’d find out eventually what the shape was, it represented a sort of retroactive “taunt”.
