I don't think that Ghost Pro should protect you from No Man's Land. Ghost has too many perks already; Why give it more? Ninja or Ninja Pro should be the counter to auto-turrets, if anything.
I think Ghost (Pro) should protect you for a short period for time. (i.e. 2 or 3 seconds). I also think Ninja Pro should protect you for a short time. But too long and people will just camp out.
I think the only perk that will get you through it will be marathon/lightweight.
