Hi Apate
Although that seems like a sensible choice and I might well be guilty of having taken that approach (departure!) in the past when no published departure was available, it doesn't really give you protection. The missed approach procedure generally starts before or at the runway threshold at a significant altitude, whilst a departure (unless designed for helicopters only ) starts at a point 5m above the departure end of runway (which includes any clearway), so the protections for both procedures are very different.
