Tedd's just like "nope, not saying anything you can't make me".
The standard lesson a character should learn in this situation is "you know what? I'm fine just the way I am, and I want my doll to look just like me!" Of course, a standard real life situation wouldn't involve magic technology that can safely transform you while easily being reversable and literally won't work if the results would be physically harmful, which I have trouble believing 99.99% of people wouldn't use to varying degrees. If this technology existed, I'd at the very least have hair worthy of the cover of a romance novel.
And I guess any doll made based on them would be made by a doll maker or something instead of magic. Probably.
