Can I lower the diamond and still keep a flush fit wedding band?

I am customizing a ring with a 0.85 ct round diamond on a 1.7 mm band, and I really want a low profile look that still allows a wedding band to sit flush. Is it better to reduce the bridge height or set the stone deeper into the basket? How low can you realistically go without compromising on durability or light return? Any tips or examples would be helpful I don’t have CADs yet, just trying to get a clearer idea before finalizing the design.
