Thanks to all who offered suggestions.
The suggestion from Fish did in fact work for me as a proof of concept.? I tried that first as it seemed very straightforward.? I booted a shadow copy of my main system.
I created a user VMUVM on level 1:
USER VMUVM VMUVM 8M 16M BG
?OPTION ECMODE
?IPL 6A1
?CONSOLE 009 3215
?SPOOL 00E 1403 A
?SPOOL 00C 2540 READ *
?SPOOL 00D 2540 PUNCH *
?DEDICATE 6A1 7A1
?DEDICATE 6A2 7A2
?DEDICATE 6A3 7A3
?DEDICATE 6A4 7A4
?DEDICATE 6A5 7A5
?DEDICATE 6A6 7A6
?DEDICATE 6A7 7A7
?DEDICATE 6A8 7A8
?DEDICATE 6B0 7B0
?DEDICATE 6B1 7B1
?SPECIAL 0C0 3270
?SPECIAL 0C1 3270
?SPECIAL 0C2 3270
?SPECIAL 0C3 3270
?SPECIAL 0C4 3270
?SPECIAL 0C5 3270
?SPECIAL 0C6 3270
?SPECIAL 0C7 3270
?SPECIAL 0C8 3270
From inside the IPLd VM, here is the what it looks like:

Now that I know how to do this, I still realize that i need to separate the level 1 and level 2 system DASD, at least where write conflicts will occur.? I'll also need to work on the 2nd level directory.
There were no VOLSER conflicts reported doing things this way.
I'm open to suggestions as far as options/settings for the VMUVM.? It would not IPL without ECMODE, so I know I need that one.
