I stand 5'5" so I'm finding the 16" one zenith eyepiece height would require a small step ladder, not sure I want to be standing on a step out in the dark to view.
I've found it's not a problem with my 16". My step-ladder has a handle on top(4 ft), which is great to hold onto to stabilize your body(even when not standing on it), and with only one step up, I don't feel like I could fall far. It's not like being 10' up in the air or even 6'. Unless you are particularly clumsy or fall prone, I wouldn't be too concerned. Also its only necessary when looking very high up, from horizon to 65° you're on your feet, and there a lot sky there.
I've also considered a "dob pit". Like a firepit, just 6-12" down, with a paver bottom, just wide enough for the scope, to put a taller dob in so step stools wouldn't be needed. You might sacrifice a some degrees of viewing near the horizon, but that's likely not good viewing anyway. Not sure it would work, but it's brainstorming.
