Wilky,
Just a thought and I speak as another mid-life career changer but if you do end up in the low cost sector (which unless you're very lucky you probably will) then from the point of view of work/life balance I don't think you will be able to match your current employment. I get 108 guaranteed days off a year, you get over 200! I do probably also get a further 30-50 stby days where I often don't get called. Flying is more enjoyable than many jobs on an hour for hour basis but after a while it isn't more enjoyable than taking your family out for a bike ride or watching movies or chilling out at home!
You are also currently earning about the same as someone who is about 4-5 years into a typical flying career (Unless you land a dream ticket like BA from day 1)
I think a job that gives you so much time to do what you want is quite appealling! Just a thought - not sure if it helps.
