I have a muuuch better idea.
Small Form Factor power supplies.

Look for those, i have a couple of HP pulls at work i can take a look at and figure out its ratings. Plus, this enables the use of soft-start as well, as this was being worked on earlier for the SE/30.
Want smaller?
ITX power supply:

The only pitfall with modern power supplies is the -12v rail. Its rarely used these days, so the current max output has dropped from 0.5 to 0.3a on alot of them. So, Someone needs to take an ammeter and put it on the -12v rail of the SE/30 and find out what the max current draw is on all conditions, including reading/writing floppy and playing sounds.
But out of all of them, the Apevia brand seems to be the best suited. Looks small enough, and has plenty of power capability. Limitation is the -12v rail. So This has to be tested... And with ATX, You get Standby ability with PW-On signals. So someone can tap into the VIA chip to get the shutdown signal, and tap into the ADB plug to get the PW-Key signal, and run them into a PIC or Atmel based board that is powered via the standby 5V.
So, when pressing the power key the PSU will come on. Like an ordinary mac. And with the proper extension from another thread, shutdown command will turn the mac off.
