I don't think that I would be pendantic about missed approach flight paths being able to be overlaid on the departure OEI flight path.
Like many things in this game .. it all depends .. especially if one throws in a failure during the early missed approach.
Consider that the approach may be at, say, full flap and an approach speed appropriate to that flap deflection. If the takeoff is based on a small flap deflection, then the clean up distance OEI will be significant and the achievable gradient OEI will be not very much ... could put the aircraft in an unenviable position. This is why the more thoughtful airlines look at the situation analytically rather than using the finger in the wind technique ...
