Hmmm embeding python code into the cr2. Um not up on cr2 files... but can you include comments into the cr2 file? The basic idea would be to have the python code commented out in the cr2 file. Then instead of using the poser library to load a figure into poser you would use a python script. It would look at the first comment line which would have um a tag (pscript) and look for the last comment line which would have a tag (/pscript)and then run the embeded script between the two after loading the figure.
