Here is I made one for converting DAZ Gen 9 Toon Floating Iris to CC eyes and quick job fixing eye sockets. Tweaking caruncle is optional (you may move it outside of eye socket altogether or hide with opacity map if desired). Got to have some experience with Blender Edit/Sculpt modes. Sorry, no comments - just screencast.
You may also need to tweak eye movement blendshapes for perfection in CC Face Editor using Proportions mode.
