Life Return

I'm planning on making a REALLY old life return master. Will you allow the use of life return to control the body into becoming younger for a certain time? I'm planning on giving my char the ability to take forms that she had when she was younger (Like when she was 8 or 61 or even 5 months old) kinda like mosquito from Soul Eater only more reasonable and one piece-like. Since Life Return allows the user to control different body actions, I thought that a master would probably be able to control aging at least for short bursts.

There are plenty of life return uses so don't worry about that. Now the kind of grey area I believe would be that overwhelmingly strong mastery of it. I say go for it and see what they say. They can only tell you no.....

*eye twitches* This is practically using the Devil Fruit I created for Ranyx, but with no drowning disadvantages.

Well the same applies to the people that control blood with it....
