Each night an automated process here uses DIRECTXA to write a current copy of the USER DIRECT file (extracted fresh from VM:Secure, and with an "adjusted" DIRECTORY statement) to a DASD different than the production sysres.
It would only be used in a wildly unexpected disaster. We already have a standand-alone minimal z/VM 'rescue system' I called the "VM Operating S ystem Hipervisor Tool", naturally residing on it's own mnemonically labeled sysres: VMOSHT Those, and various other recovery bits and pieces help me sleep better. At night of course, never during the day! It's simply a matter of remembering where all the bits and pieces are should something goes bump (or scraaaaaaaaaaaaatttttch) in the night that makes it more difficult to sleep. But I've never needed them... so THERE! One usually only need recovery tools when one didn't create them. Prepare for the worst, enjoy the best (z/VM)!

It was fairly easy. On another CPOWNed pack, use CPFMTXA to format a few cylinders and mark it as directory area. When you do a DIRECTXA, it reads the directory record: DIRECTORY 123 3390 520RES and put the directory on virtual address 123 volume 520RES. Use rexx or something to update that record to 124 and 520W01 (for example) and do the DIRECTXA again. I don't know how to do it nowadays, but when we IPL'ed, we had a option to say what pack the CP System areas were on. Come to think of it, that was in the DMKSYS days....VM/SP. wow! My guess, is that you would need to put a CP Minidisk (such as CF3), on the same pack as your direct area, and IPL from that pack (when necessary). But I'm just guessing... So, in your method of putting another DRCT area on a pack, how would you ever use it?

By the way, even though you can bring any directory online while the system is up, remember that the system will search for the first DRCT extents it can find at IPL (see the CP Planning book), which may not be the directory space you activated with DIRECTXA.
