Hi Futurist,
I don't know what sort of research you're done into orchidectomies, but removing the main organ of testosterone production may seriously compromise your libido and the ability to maintain erections.
Another point of concern would relate to any future, if at all, genital surgeries, as the longer you wait post orchidectomy the greater the atrophication of any donor material and the scar tissue may also compromise any donor material.
Surgeons who conduct neovaginoplasties are best to perform orchidectomies, as they preserve as much martial as possible.
You may need to do more research into the side effects of your plans.
Speak to you as soon as I paint the verandah.
