If neither you nor Mrs. Kije have UK citizenship and/or right to work here plus only having FAA licences, you're facing a whole heap of paperwork and permissions plus converting to JAA.
In order for Bristow in the UK to employ someone from overseas, they have to prove to the Home Office that they cannot find a suitably qualified and experienced EU citizen to do the job. That might be a tad tricky as there is not a great deal of recruitment going on at the moment.
You will have to sit the 13/14 JAA exams although with your hours, you may be exempt the classroom element. Your conversion for flying for CPL will be training as required and the IR conversion is a minimum of 15 hours plus a twin-engine rating.
Have you considered the cost of living in Aberdeen? If your wife cannot work here (and it's unlikely if you are both US citizens unless she has a qualification that is needed - we're short of bloodstock trainers apparently!) then supporting the both of you on a co-pilot salary may be difficult.
Your plan as it stands needs a lot more research and I'm not being rude or sarky!
Cheers
