SCRs like NXL0840 NXPs can be used in this type of applications to save component count and board space. Ofcourse, your circuit has a benifit of configuring holding current. Good Idea !

Good idea! It is a simple bandage to circuit that needs special turn-off.

I think it is a good idea to have a resistor in series with Zener diodes on 48V side. Once you go above 27V+27V+LED voltage the current rises very quickly and the LED might get cooked. Happened to me.... Anyway good idea.
