If you don't get that NS job, where are you going to after that? Police/AA need 1500-2000 hrs minimum with twin, night etc...Corporate, still need lots plus type rating, or if you're really lucky get to work for a wealthy person and dance to their tune whilst scraping to pay off all that training.
Even at your age, you're behind most, listen to these people and show your wife this thread and see if she thinks moving to Aberdeen is worth it YOUR dream.
