Just refitting the refit suit with the shrinkwrap takes only a couple of minutes, but has some weakness. I think one has to assure that the most important body points correlate smoothly. A direct projection of one mesh to the other tends to move some points not as intended. If I had a more beautiful fit for the refit suit, the outcome would come out better. So, the problem is to morph the refit suite properly. But its a managable task I would think.
