What happens if there is no +5V power when the 15V turns on, does the 
module get damaged at all?

How about a new larger current full size power supply that could 
power the same number of both old and/or new modules.

Maybe it could have normal connectors for +- 15V to old and new 
modules, with a separate 5V connector/wiring scheme for the new 
modules.

This way people with existing power supplies could add the walwart 
solution to their system, and people buying new supplies could just 
buy the new supply and not have to deal with a messy power system 
using two separate power cables/switches/etc. per cabinet.

And while you are designing a new supply, could you please add remote 
on/off capability, so that we could use a non-powered front panel 
switch if we want to. The remote part of the circuit could be 
jumpered so that it could work as either a normal rear panel or 
remote/front panel switched system. It could also have power status 
lights on the front panel for the DC power rails/AC power/standby/etc.
