My plan so far is just to go forward with HRT, body hair removal, and growing my hair out, until I can’t hide it anymore, then I can just be like, “Welp. Guess I’m a girl now lol” but not sure how well this would work in practice.

I think that's sorta my plan for work except the planning to be a girl. Started with growing out hair and haven't started body hair removal yet (too busy during the summer). Didn't really worry about the logistics of it though. Started HRT mid-April and sorta hoped I wouldn't have any issues hiding it through the summer for work (while simultaneously wanting the changes to happen faster).

The not being out to my parents yet thing led to the slightly awkward situation of swimming topless at my parents a couple weeks ago and being asked by my stepmom again if I'm trans* while we're swimming because of the conversation (pretty sure there were not noticeable changes at that time so I don't think that was actually related). Topless estrogenated bodies should be normal anyways though.

*technically she didn't use the word, but it was implied.
