The problem is WOL still requires you to have at least one computer
already powered up, then that computer can receive the WOL
No, it doesn't. A router that can send the WOL packet can wake a PC
listening for it. No added PC necessary. Just that the PC you intend to
wake up needs to have WOL built into it.
Alternatively you could use a router that has a serial port and use that
to
control a relay that will listen to RS232. Bit more of a
jump-through-hoops
sort of solution though.

If my PC has no power applied to it how can it possibly "listen" to
anything. I want it completely powered off, not on standby.
An ATX pc is never really off..
In fact part of the MB is still under power..
how do you think the pc turn on just by the press of a small momentary
switch...
you can even see that the MB is under power by looking at inside the box
while the system is supposed to be off. you will see at least one led on..
