Yes, you could. I most certainly would. Maybe a bit ambitious as your first
real project with CMS Pipelines.

What the trivial examples did not show you is that "command" takes a stream
of commands to issue. That makes sense when you generate the commands from
another source.

For each command issued, the return code is written to the secondary
output, then the command response is written to the primary output. The
reason for your pipeline stall is that the "fanin" expects to read primary
input first, then secondary input. If you really just wanted to merge the
two, you could "faninany" (and get the return code first) or you "buffer"
the command response and put the return code after it (but that only makes
sense when you just issue one command).

What I would probably do is to use the return code of the VMSECURE command
to track which commands failed, so that you can review them, or correct
them, or whatever makes sense. I've done things like that when running
commands on a group of Linux guests and sometimes those things would fail
for unexpected reasons to be explored.
