Of course it's possible. x264 uses the the motion estimation part of x264. 
If you really meant "Is it possible to abuse the motion estimation part of 
x264 for something other than encoding h264", then you'll have to specify 
more precisely what you want.

Are you looking at the mv of an intra block, or an unused direction in 
bidir? Fail.

Are you complaining that an encoder's motion estimation only minimizes 
block-wise residual, and doesn't find real motion of objects in the scene? 
Yes, motion estimation for vision is harder than motion estimation for 
compression.
