You'll get a result.

I've always stated the following regarding hair:-

Wardrobe Wizard can convert hair but its not always the best method. Simply scaling and positioning the hair and parenting it to the head can often produce optimum results.

Irrespective of conversion method clothing acts like clothing, hair acts like hair. They'll only need the same jointing and morphs if the hair follows the body line very closely. Most styles and in particular long braids, do not.

By all means convert to see what result you get. Its very quick and requires little mental effort. However remember there is a Plan B, which I've frequently stated should in my view be Plan A.
