To deal with the eye issue so you have a reference, save out Roxie's eyes as a obj, then hide the normal ones, import the new ones. 

Just keep in mind that the new eyes should removed before saving the scene again. So should things like the hair that loads and forgets Roxie....

Before you save the scene, double check that the character is zero'd, and that includes body parts.

Another thing I do to skip some of this is use a stripped rig for making morphs (dev rig that is locked rotation and offset wise). It will accept textures, etc...

When using the Dev rig there is little work involved to save it out the morphs as an injection, and zero chance of forgetting to remove a characters morph that shouldn't be in the injection...

Scenes without lights and textures that emit so they show with out lights are handy as well.
