It would work if you "charged" your unarmed strike with that spell, however. You have to hit the higher, normal AC - but then you simultaneously Boot them in the Head and deliver that harm spell. One failed save is all that stands between a nasty Boot to the Head and a truly spectacular Boot to the Head.
Makes a Monk's Robe worth it just for the free 1d8 improved unarmed strike, IMO.
