Hi Alexis, I had the same idea as you! I wanted all of the amazing affects of hormones and to look in the mirror and see a super model, but to somehow have no one notice:) I started on a low dose in August 2015, and ramped up to full transitional levels by June of last year. Once I saw and felt the beautiful changes (both mind and body) taking hold, I realized I could not turn around. I was very scared at first that someone might find out (cause it's pretty obvious), but surprisingly, people don't pay too much attention. They have their own problems to worry about. As time went on, I begin to let my guard down, and honestly, every time I did it ended with an infinitely more positive experience than I had ever imagined. Even coming out to family was surprisingly positive (although it's brought some significant but not insurmountable challenges to my marriage).
I am still somewhat stealth, maybe androgynous, in many work situations, but I present female outside of work, mostly. I get some funky looks periodically when I'm in male mode, and get mammed periodically (feels good), but as soon as I open my mouth and speak with confidence, any periodic strangeness dissipates. I think that is a really big part of it. People will be nervous around you if you look nervous. They will be comfortable around you if you look comfortable and confident, male mode or female mode.
Over the past few months, my fear has eased hugely and I'm really at peace. While I could probably act male and hide it indefinitely, its often times more of an effort and more awkward presenting male than female. I am working up the courage for my next step, which is full time permanent transition and purging of all things male, hopefully very soon.
Anyway, I really have had a great personal experience with a slow transition, and it gave me time to build confidence with (seemingly) less risk.
Breasts... mine are a B cup but I can hold them back with a tight sports bra. Under Armour makes an awesome one with a super flat band.
Weight loss... yes, it won't get easier! I did Weight Watchers and it worked great. There's an app on iOS that's almost the same, Trac Bites.
Good luck!
