Your plan sounds similar to what I did when I started HRT. I kept the supporting stuffs but stopped PM back then and next day I was on estrogen. I kept things simple at first and started to add things in swloly one by one. This helped to find what works and what doesn't, too bad I didn't get a startingpoint blood check, I got my first labs was it nine months in.
When you do it like this, it'll be easy to troubleshoot NBE items if something doesn't feel right.
