Okay so I used WRAP to transfer textures and displacement from xyz map i have to my model. I followed Sefki's video to do it. It's very straight forward and simple, and on if you don't have wrap they offer student version or 30 day trial so you can do it either way, but I can advise you to get it. ( I probably will too after my trial ends)
I fixed up the transferred mesh and checked how the projection worked. After this, I started detailing , using the multi channel face textures form texturingXYZ mixed with a lot of Pablo Gomez's skin brushes. I have most of the stuff on seperate layers to keep everything easily adjustable.
As far as modeling I have left 2 necklaces, and a pair of sunglasses. The next step will be exporting out displacement, normla and cavity maps from Zbrush and start texturing, where I'll mix the XYZ texture with the one from CC and I'm pretty sure I will hand paint most of it.
