Have you checked out the RDNA beautiful breasts package? They have morphs like "rosebud" and "youth" and "barely there" that would prob work well for you.

theres the link but be aware the main page promo pics are fogged out in the frontal nudity, youll want to check out the sample pics at the bottom of the product page to see some of the morph promos.

hope this helps,
