Even if you finally redirected and focused the light to a
small spot, the phase differences caused by the variations
in distances traveled by the various ight waves would
produce an awful lot of phase distortion.  The visual
effect would still be a diffuse illumination and softened
shadows, although brighter in a smaller area.

But would it be more fun?  ;-)
