I have reflected on this question many times and the conclusion has been the same every time. While there are advantages to living your life in one form I don't see how it would improve so drastically by transitioning to full time living.
I seemed to have fused both male and female animas into a formula that works even if that formula is not perfect. There might always be a little nagging question of what if but I chalk that up to the gender dysphoria. I have gotten to know how it works and what I need to do to feed its demands.
The best tool in my arsenal has been to be completely honest with myself and truly reflect on what is required. Life is never perfect for anyone and while we may have gender issues others grapple with depression or physical illnesses.
My having developed a perfect comfort with clothing, makeup and mannerisms has been pivotal and all that practice didn't go to waste. I have long ago outgrown the confines of my own space and my female persona must exist in the real world in order for me to feel whole.
It feels very much like I have attained a comfortable plateau where I can continue to exist indefinitely and this is extremely reassuring to me.
