Question Person and height map

[hazmhox]

Before I start to debug the whole character and components through scripting inside VaM, i'm gonna try to ask, maybe someone knows.
Is it possible to add a height map ( with scripting ) to a person's shader ?
I'm trying to reproduce some skin detail for Eve, that would look like something like that :

This one being the best example :

I'm talking about the deep / heavy traces over the skin. We all know that the normal is made for surface details. Trying to simulate heavy deformation of the skin with the normal is gonna be frikkin' ugly.

So I was wondering if it could be possible to add an height map which would definitely be better to simulate heavy depth differences without having to dig inside the concept of morphs creation.

Thanks in advance!
Cheers.
