Do the vaginoplasty, but please leave the rest of your daughter alone. When I was a young adult (18-19ish), my ped endo actually and quite profusely, apologised for having any role in cutting off my 'enlarged' clitoris when I was an infant. Her excuse was that it was all they knew then and SOP. If it bothers your daughter when she older, let her be of the age so she can rationally make up her own mind about it.
