Hi caisson. I think it can. I exported the hair as a hairprop via GOZ from zbrush, then turned it into a figure, using the fittingroom. I adjusted it to the head and the neck and preserved the morphs. Back in the main menu i conformed it to the M4 model. Moving it around (as in the picture above) it behaved exactly the way i hoped it would. But for some reason it wasn't visible in the render.
