Hello! Long time reader/lurker and finally posting my own question 
I am in the brainstorming & inspiration phase of a custom pear cathedral solitaire ring project. I don't have THE stone picked out yet but looking at .9 - 1.5 carat stones with depths ranging 3-4mm.
I have an existing band that is approximately 4mm height off my finger (using a ruler, no calipers at the moment but hoping this is enough basic info for my question).
Would it be possible to design a cathedral ring that will fit flush with this band, or would this 4mm height requirement make the cathedral ring way too high and difficult to wear and I'm better off using a spacer band between the two rings?
Here is an inspiration photo of what I'm thinking from top view, altho the proportions of this example are not exact to my existing ring and the pear shown is also probably quite large vs. my specs

Thanks so much in advance for your help! Really appreciate it.
