Dotcomformat

I've finally started along the .com/Oakley road - and I'm so impressed by the sound 
and feel of the modules that I've decided to sell most of my doepfer/as gear.

The best bits remain and I'd like to make them all .com/motm format.
I can do the drilling/screen printing myself and for now a cheap conversion will use 
1/4" sockets but retain the small knobs, but I'm not too hot on power issues.

Is it a simple job to make them run off a .com/motm 15v supply? I can make the 
custom cable from module to supply but how do I knock it down from 15v to 12v or 
will they run ok on 15v?

I'll probably have a few 12v modules so maybe a custom board that accepts a snipped 
.com 15v feed and has a few ASys and doepfer sockets would be perfect...Anyone 
done this? I have an old 12v supply that can be adapted for this purpose.

I think this would be a great little thing for someone to sell...
