Dark Magicianj Girl- let's face it, in the series, despite that there are cards that can turn monsters into stone, she won't be turn into one, though she was frozen in one episode, but still turning her into a stone statue is way more better than freezing her inside a crystal
Stellar Loussier- this girl is from the anime Gundam SEED Destiny so petrifying her is quite impossible, given the fact that the anime is more on technology and war, not magical stuff, but seing Stellar being turned into a stone statue would be quite interesting
Rosette Christopher- here's the funny thing about Rosette (from the anime Chrono Crusade), there was an episode that show that she used and her brother as well as Chrono, which is a demon, used to live in an orphanage, but since her brother has somewhat "demonic" powers which can petrify anyone, he turned everyone into stone statue, but by accident since he cannot control his power, but despite this, he did not petrify Rosette and Chrono. Of all the people that her brother can petrify, why didn't he turn Rosette into a stone statue? It would have been interesting. T____T
Nina Sakura- to those who have watched the anime Ultra Maniac then you'll know who this character is, but for those who don't, well, Nina is a witch, though instead of wands, she used some sort of a palm computer to make magical stuff. Though despite that the anime has magical girl, there is no petrification occurence, which is why, I want to see a petrified Nina Sakura.
Suigintou- so ok, Suigintou (from the anime series Rozen Maiden) is a doll with life, which in terms of ASFR, turning a girl into a doll is included in that genre, still, seeing Suigintou turned into a stone statue is very interesting for me
Chii- she may be a robot, so what, it doesn;t mean she is excempted from petrification, infact, Chii is one of the few anime girls, in my opinion, that is a perfect candidate for petrification, seeing her innocent expression while she is turned into a stone statue.
Meer Campbell- if you have watched Gundam SEED Destiny, then you'll know this girl. In my opinion, turning this girl into a stone statue is quite interesting
Anri Hiiragi- well technically she is a mage that wears a maid-style clothing. Seeing that the anime titled Happiness! has a potential of petrifying a character due to having magic themes but the series doesn't have any ASFR stuff, it would be pretty interesting seeing her turn to stone since most of her magic backfires
Lizlet L. Chelsie- a busty maid whose original form is a tea cup.... well the description of being busthy is enough to see her turn to stone specially since the anime/manga she is from titled Omamori Himari deals with supernatural stuff, though there are yet monster with petrifying abilities to appear.
Mika Alsted Heine- a character from the eroge game titled Angel Ring, her appearance is enough reason to petrify her as she is wearing skimpy and sexy clothing.
