Hi
the simplest way is to use the free Blender pipeline tool to export your character to Blender.
Place a sphere over the head with a section of faces removed on the bottom for a neck hole.
Apply a shrinkwrap modifier and use the inflate sculpting brush to lift up any intersections with the characters face mesh
use the pipeline tool to export as accessory back to CC4 and transfer skin weights to make it conforming.
you will have to find your own flash colored skin map (YMMV)
