One of the problems is regulatory/legal ... while the takeoff requirements can be prescribed with some confidence of legal testability and operational repeatability, the same cannot be said for the missed approach .....
I suggest that the question of obstacle clearance planning on the miss is a matter better left to operator risk management planning .. certainly, the pilot is in no position to do the sums .. which need to be done by ops engineers as the considerations are similar to takeoff OEI obstacle clearance.
