To a minimal extent this has been done.  I have a 16mm film that shows 
the Zapruder film, the Zapruder film zoomed in toward limo occupants, 
the Nix film, and the Hughes film (I believe but can't specifically 
remember) merged together in four image quadrants in frame 
synchronization.  This shows JFK's movement throughout most of the ~6 
second shooting sequence in a triangularized fashion.  Although 
difficult to add new perspective to movements and shots before frame 
311, the dramatic movements of JFK's body from Z311 on clearly add 
perspective to the analysis of the direction of the shots to the head 
based upon simple Newtonian motion physics.  

The film work was done by Robert Groden, who I was closely associated
with in the 1970's.

I have seriously considered generating a 3-D image analysis of the 
shooting, but as I am sure that you understand, it is a significant 
amount of work.  A great deal of interpolation would have to be done do 
to lack of multiple vantage-point data.  Converting 2-space image data 
into 3-space projections is very complex.  Mapping the projections 
together to generate 3-D images even moreso.  Techniques such as 
key-frame animation could be used to generate moving images, but the 
integrity of the data becomes unverifyable very quickly.  At minimum, it 
would be nice to have digitized high quality computer images of the 
entire Zapruder film (and other significant JFK images) available (in 
GIF, JPEG, etc., format).  I have obtained some selected images off 
alt.binaries.misc, but they were of poor quality.  

In summary, it is a massive undertaking, but certainly could be done by 
someone with the inclination and resources (mostly time).  It's just a 
SMOP - (simple matter of programming).
