this is in direct contrast with what you're asking later:

which is obviously impossible if you want to just increase the reference
count of the objects.

you can simply create a new actor setting all the properties at
construction time:
copy = g_object_new (CLUTTER_TYPE_LABEL,
"text", clutter_label_get_text (orig),
"font-name", clutter_label_get_font_name (orig),
NULL);
