How about a freewheel unit (slipper clutch) - should prevent alt least the reversal part after the power-stroke... 
 
I know Rotax used those to get rid of resonant problems with their 912S, and if I get to the point where I have to custom fit some sort of coupler, I'll consider trying it.  
 
Also, visual impact is one thing, that may have NOTHING to do with the actual blade behaviour.
Unless you take a strobe and watch, you might get some "funny show" - frame rate of the video, etc. 
 
This is true, but there's no optical illusion I know of that can make the prop move fore and aft when viewed directly from the side (in the arc).  What you see is also consistent between viewing with your eyes, and the camera, which is another indication that it's real.  A really high speed camera would be better for this though.
