The first thing you should think is how to legalise your immigration status in Europe. If you have a wife that holds UK passport, that would give you a right with proper visa and application process to work in UK. However most of Europe tends to be part of the Schengen agreement and alas you would need to obtain a schengen visa (D or D+C) to work and be based outside UK. Your family connection would not help as UK is not part of the Schengen and unless you have immediate family holding passports from those countries you would not be qualified.You could try to find a company to organise that for you, but I fail to see why as there are hunderds of pilots without a job that do not need any extra help.
Once you have cleared the immigration issues you can start working on your European licences.
