Using Z-12 is a great base.
I question having most of your Garmin suite on th essential bus. When do you need
to turn off the main bus? Smoke in the cockpit is a big one. You don't 't know
which wire orbox is smoking, so you kill the whole main bus. The more things
you put on the Essential Bus, the more likely you are to not shut off the smoking
stuff... We usually only want REALLY Essential stuff on the Essential
Bus.
Then, after your smoking elements have gone to sleep, if you need something on
the main bus, you can shut off everything on the main bus, turn on the Master,
smell for smoke, try that item you need, smell for smoke, and get on the ground.
Now comes the nightmare. The smoke was being let out of something you really need.
From my quick review, you have two EFIS, so gyro and altimetry functions are
still available even if one EFIS is down, but you only have one GPS/NAV/COM.
Good reason to have fully charged and engaged EFB and know how to engage it's
backup display and Nav functions....
