I wouldn't do it!
It sounds like you would have very little couple time, which could be hard on your relationship, especially if you start to feel lonely and resentful at the loss of your previous life. Take the money out of the equation and is it still the ideal scenario? Would you make such a life changing decision for no pay change? You say you will be setup for life in ten years, is your relationship strong enough to withstand such a big change, for the ten year mark to be worth it? plus if you have children will you be ok with DH not being home much???
