No, but you can do it by adding an extra package:
Rename the current libcupsimage2 to e.g. libcupsimage2s
then add a dummy package
libcupsimage2 that depend on libcupsimage2s and libcupsfilters1.
and change the shlibdeps accordingly, and rebuild libcupsfilters1 so that it
now depends on libcupsimage2s.
