first off, thanks for this lovely review! I really appreciate you taking the time to put your thoughts into words. Im glad you find the characters satisfying! we wanted to put as much incentive as possible to go out of your way and learn more about each character, so its good to see their intricacy is being recognized.
as for your questions:
there will me FtM transformations, in fact version 0.5 has one already! (Magnificence -> Magnus)
we do plan on allowing more routes for lewis and rhianna to get together. we will be seeing more of Lewises king route when we get to challenge 3 in January, so stay tuned!
the approach dialogues are something that we will update as we go, for soldier akarion specifically, his unique approach will show up in 0.5!
