Firstly this crew has all my sympathies and of course the final responsibility rests with the Commander.
It can be easy without realising it to end up in "reactive management" as opposed to "proactive management". If the Notams are that ambiguous (and I wouldnt be surprised if they are in this case) then perhaps the best decision would be to divert before even departing. Of course this would not be very popular. In the late 1960s BALPA named various airports as Black Star Airports due to, for example, a lack of basic approach aids like no precision approach or even VASIS on certain runways. Within a very short period of time these airports were brought up to standard. Perhaps it is time for BALPA to conduct a similar exercise to name and shame airports which do not meet certain basic standards.
