Can the Cycles Vector Pass in conjunction with the Vector Blur compositor node be used to create "smear" instead of motion blur?
To be clear, by "smear" I mean this sort of distortion representing between-frame motion in traditional hand-drawn animation:

This would be for adding a more hand-painted feel to non-photorealistic renders.
I have tried a few different approaches (which I might post detail on at a later time if it seems it would help)... but I have not yet achieved any usable results.
Maybe a different approach is needed (and I'm getting more ideas to try as I compose this question).
I'm curious what the community might come up with.
Update: I've got the motion vectors displacing the image. So this is the basic idea.
It is having an effect, but it's not so accurate... yet. Maybe with some tweaking it will work. I need to study more closely how the mapping of the Vector pass works.
I don't think I'm supposed to just be adding the two sets of XY vectors together. But this was a quick way to verify that there is an affect.
