It doesn't have to be perfect for every situation.  Basically, anything would be an improvement over current options. 

And you could make other versions later.  Maybe higher and lower res versions.  Middle part vs. side part.  A skullcap meant for styling hair vs. one meant for dynamics. 

Maybe even skullcaps meant to be used together.  Kirwyn did that with one version of his Genesis hair.  He had two skullcaps, one inside the other.  For a distance render,  you could use just one for faster processing.  For a close up, you'd use both.
