I have a question about a character I am considering apping. Essentially, they are two different characters who share the same body with no way to separate them. It isn't a soul inhabiting a body type of deal either, but under certain circumstances, Character A will transform into Character B, with physical changes included (like change in hair/eye color, etc). When the stimulus ceases to exist, Character B reverts back to Character A. They both have their own distinct personalities. At the same time, they're not totally different. They share the same parents and if anything, they're more like brothers in one body.

Because they're so distinct and under normal circumstances (ie each having their own body), they would certainly have to be apped separately, I thought I should ask if you feel that would be the case here, too.
