Imagecache Profile and Avatars Selection coexistence

Recent versions of http://drupal.org/project/imagecache_profiles support Private file system. For example, I have the "Picture image path" in User Settings set to "original_size_avatars" (relative to PrivateFiles, outside of web server root). I would now like to disable picture upload alltogether and use Avatar Selection instead. To this purpose I was thinking to symlink/alias avatars_selection -> original_size_avatars. Imagecache Profile would then create smaller versions (for teasers etc...) in a separate directory, and that should be transparent to Avatar Selection... I can't just try it now because I must work out other probems first, but would like to ask whether my reasoning is correct or not. Thx.
