The big issue here with currency (recency) and experience is not the ability to fly the helicopter - it is the ability to make decisions, either before getting airborne or once in the air.
Planning to fly that route with the forecast weather is one of those areas where you might assess it as marginal and have a viable plan B (rtb or divert or land) or you might take the risk and push on until you have run out of options.
The first option might be that of an experienced pilot or a wary, less experienced one - the second option is likely to be that of someone who has convinced themselves they are good enough to cope with whatever happens and is often the precursor to many CFIT accidents.
I wonder if they ran their grand plan past anyone who didn't work for them so they might get the 'voice of reason' to tell them the idea was a crap one.
A frustratingly pointless loss of life.
