I think it could work for you, and it's great that you can find a happy medium without disrupting your world. I was on HRT for 5 years to allow for adequate feminization, and to save for initial FFS, before I went full time; so I know from experience that most of us can be on HRT long term without transitioning full time. HRT affects our skin and fat distribution so most of us look younger from the treatment, and also causes breast growth, but that can usually be hidden, and if not most people will think we have "moobs", and for most of us it takes a long time to get hip and butt fat distribution, and even then it's not as prominent as what Cis women develop, which is why black market silicone injections are unfortunately in demand, as well as fat transfer, and hip/butt implants. People will notice when you grow out your hair, have your eyebrows shaped, have electrolysis, grow your nails, start using female mannerisms, speak with a female/feminine voice, and walking femininely; so basically most people will not know that you are trans just because you are on HRT.
