Should be easy enough. Perhaps specification of certain thresholds of height could be walked off of and it not affect the hack? For example, doing -safewalk .0125 would allow you to walk off a threshold if the distance between the block beneath your feet and the one adjacent (where you're trying to step) is about .0125 lower than the current block. I believe this would allow one to walk down snow layers that are stacked on top of one another.
The current safewalk implementation is just treating every action as if you're sneaking. The tolerance may be possible depending how sneaking is implemented
