This does run into a bit of a peeve for me when it comes to TF/MC content: If you are doing a complete physical transformation and personality rewrite, there is no reason to pick particular targets beyond a desire to murder.
At least it's not the full "go to great effort to kidnap $FamousPerson, then turn them into yet another identical near-mindless big-titted blond bimbo," version.
I like when feminization/gb is involuntary alright, but this is just straight murder and creating a new person from the corpse and of course, some people might be into that, nothing wrong with that, but it'd be cool if it had a different tag, like cordycepsification or something
