I'm certain I was reading more into @ahoeben's response than was warranted, for which I apologize. After numerous hours and several failed prints, I sooo wanted @ahoeben's answer to explain why this isn't possible.
This makes sense, as I'm not printing a simple shape. I'm printing 3 domes of varying widths, stacked face-down on the build plate (first image is just for shape reference).
I've set different layer heights in Simplify3D and will reply to this thread with results. Thanks for your explanation.
