it's not a secret: current trasnsgender technologies is not ideal.
This thread is dedicated to discuss how can we improve transition using science power & future techs.

My ideas:

1) "I Will Fear no Evil" (Robert A. Heinlein) -way: use a donor body after donor's brain dearth to transplant brain inside it.
Possible problems:
1.1 immune system compatibility. Can blood–brain barrier helps??
1.2 very short timeline to attach brain to blood arteries in new body. We can use low temperature for brain, but it can give us maybe 20-30 hours, not more
1.3 Too comlicated process to attach all arteries and veins, and nervous

2) edit genome, and change Y chromosome for X(for m2f), or one X to Y (for f2m) and 3d print a new body without brain using 3d bio printer. What will happen with immune system compatibility?

3) Near future(?)
transpant vagina + uterus (for m2f) or penis(for f2m) and gonads from dearth donors
immune system compatibility problems :(

4) hack immune system. How can we do it? And force it to not attack transpanted organs.

5) nanobots in blood/cell - so, it's a godmode
