Candy Cane Tie, I'm currently doing this, and have been for roughly a year. I consider myself a pre-T, pre-op FTM, but am pretty successful without either.
I'm lucky enough to have a male birth-name, so I didn't have to change it. If you really want to go full time, I'd suggest getting it legally changed and switching all of your I.d. and credit/debit cards. My experience is that people don't see the "F" and just look at the picture, name, and birth date.
With the other things you mentioned, I'd add working on male body language and speaking like a man; it's not just about making it lower, it's a style of speaking. For me, mastering how to speak like most guys do was the tipping point for me being regularly read as male.
It's definitely possible, but don't be surprised if people treat you like you are younger than you really are, which sometimes comes with a lack of respect or coddling treatment... Which is my current reason for wanting to start T. I get treated like a guy which is great, but I don't know if I'd ever be treated like a man without HRT. It's OK for now since I'm in college, but I feel like my time for getting away with it is limited.
