Sure this is possible. You can burn the image resource files to a CD\DVD and setup COP to point to the local drive for the image retrieval. This is actually documented in the ROMS guide! See pages 147-151 in the v2.1 guide.
I've not had much exposure to CCM but i do know that there are limitations between CCM and OVCM and i guess that COP is one of them. I don't think CCM is intended for use in a Enterprise enviroment - which is where you'd use COP - so maybe you cannot use this feature.
