Sorry brother. I could not recall at anytime MH have 737-400 female pilot whether she is F/O or captain. I was there. It did not materialised. As for the World Airways contract, the planes were leased with their own cockpit crew which at a few occasions, I have seen female cockpit crew at the ODC.
As far as the crew bunk is concern, as long as you keep your hands to yourself there should not be a problem. If the cabin crew can share the bunk during their rest hour, I don't see why cockpit crew can't do the same. I have a few female pilots on my long haul fleet. I don't see any problem. The problem arise when you created one.
