Calculate the greatest decal warping present

Is there a way to tell what is the greatest ‘warping’ present (the highest amount of bending present) in a decal as it moves based on mouse cursor line trace.

e.g. if it hits part of a straight wall, it would return 90°, 0° if it is completely over flat ground with a positive z normal (180° if the normal is going in negative z space).

This would be a handy alternative to a series of expensive multi spherical or line traces based on impact points to generate the angles.
