As I see it, your NPN mosfet would go between Q1 and the return to 0V, parallel to the 0V return from your device attached to H1 (and the battery). There may be reasons why this wouldn't work with the L317, but I am too inexperienced/untutored to know about them. More expert advice welcome.
How does D2 work?. Why isn't battery 0V connected to wall wart 0V?
How are you sensing when the battery needs to be charged, or are you assuming it will just trickle charge?
