Moving from sex-only BDSM to lifestyle D/s within marriage?

Has anyone done this? I'd love to know more about how you approached it etc? My wife and I have a free use, kinky sex life but I am keen to explore expanding our D/s in a more everyday lifestyle direction. I think if done well she would love it. But it's a big risk of a conversation and we are 10yrs in with 2 kids and a mortgage. She is the love of my life and I don't want to ruin anything. Plus of course it would need to be super careful given the presence of our kids. Any thoughts/advice welcome. 🙏
