There is certainly radiation pressure pushing outward
from a 1/4WL thin-film non-reflecting surface even
though the reflected waves cancel each other.

Actually I agree, but it's all from ordinary reflections, rather than
from backscattered interference or anything else from the 'square root
of negative one' axis.
