[cups-devel] help me understand cups-files.conf

I'm a complete newbie... and need to understand:
OS X 10.11 El Capitan, CUPS 2.x, SIP workaround for open source CUPS 
filters/backends/drivers.
In cups-files.conf, can I set the Directive ServerBin to 
/usr/local/cups, so I can install OpenPrinting's executables there? And 
then do I need to setup a "mirror" of /usr/libexec/cups there by 
creating all the directories identical to /usr/libexec/cups -- with 
links from /usr/local/cups back to the protected executables in 
/usr/libexec/cups?

This is just my first idea about how to do this -- I'd welcome any 
suggestions.

Thanks,
Greg
