Two obscure instances.
"The Machine: Pride of Pinbot"
A pinball machine with a "building a robot woman" theme. If you play well enough, she enters a "Metamorphosis" stage and becomes human. She's also a non-process giantess, according to
The backglass.
"Starbears"
An obscure animated movie. One of the characters is a robot bear who is shot near the end of the movie, and saved by a deus-ex-machina force and turned into an anthro bear girl. Cute, but in the "litter of puppies" way, rather than the "I could tap that" way.
