The 5V rails are regulated down from 10V, the 15V rails down from 20V, so somewhere between 25% and 50% of the power becomes heat in the series transistors. A new A6 with four high quality DC/DC converters and some extra filtering would be a really big improvement both heat and efficiency wise. It would be trivial to make such a design able to run from a 24V Battery supply input as well I havn't tried to measure the power-drain on the four regulated rails, but from the short-circuit resistors it looks like less than two amps on +/-15V and less than 10 amp on +/-5V ones. >Yes, you can build your own UPS.

Taking the detour around mains is a bad idea, everybody who can are moving away from it. >What did you have in mind for a power line monitor?
