Yep: the Oxford Diffraction 'CrysAlisPro' package includes a tool
working
in precisely the same way: generating 'pseudo-precession photos' through
pixel-by-pixel analysis of all of the raw diffraction images...

This is actually how it is done in the Bruker software (Proteum2). It
collects the relevant pixels from a whole series of xray images and
generates a simulated precession image for a chosen zone. It can be
very informative.
