FWIW, I had consults with Drs. Ousterhout and Spiegel. Ousterhout suggested I get a trach shave, Spiegel suggested cheek implants, and both of them thought I should get a lip lift. I said no to all three, but asked for a some neck lipo, which hadn't occurred to either of them.
Bottom line: You're the best judge of what you need to be happy. If you think a feature - especially a soft tissue feature like your cheeks - is likely to change a lot on hrt, you can always put it aside for a while and reconsider it a few years down the line.
