The simple answer is to work as a developer for half the year then take the other half off to go do whatever gives your life that meaning. It's simply more cost effective to do it this way than to try to find a "meaningful" job that you can pick up with zero experience that will still bring in enough to support your family. Incidentally, if there exists a job orthogonal to your skill set as a developer that you can jump into and make upwards of half your current salary, that's a good sign you're not billing enough today.
