Faced with a similar predicament myself, although I more than 4 times the quals required for the airlines, I just turned 50. The similarity is that even though we not make it into the "airlines" those that do will leave spaces to fill and pilot training isn't keeping pace with the vacancies.
My suggestion, for what it is worth, find an aero club or dedicated school and get your rating back then work on the weekend. Get a feel for it again and offer your weekend employer a bit of rostering flexibility on the weekend. Best of luck with it.
