Hmmm....It might have been interesting but I don't think people would have gone for it. The whole reason I hated Interview With A Vampire was, as others have mentioned, the whole child sexuality angle with Kirstin Dunst. Although it made an interesting plot twist as she emotionally aged and didn't physically, it was still a bit sick for my taste. And especially in the 60's, when television didn't have to go for shock value every five seconds to get ratings, it might have been too much.
