a flt ctrl problem will provide sufficient time to burn off and get the wt under control= for a smoke/fire/medical emer etc the land flaps(in most cases are available)= hence a combination of low/no flaps+over wt landing is a very remote possiblity
assume rtow is vmbe limited and you take off(using max v1) followed by an immediate return,remember v1 cannot be greater than vr which inturn cannt be greater than v2, which by the way is about 20% above vs. on the return vref for say the same wt is about 30% above vs. assume a stall speed of 180 kts so we are talking about absorbing the energy equvalent of 18 kts!!.with the luxury of reversers and longer r/w I dont see a problem
