I know in the lore it is very rare, nigh impossible, for sisters to fall to chaos(Miriael Sabathiel). That being said i have always thought the fact that sisters play into such a religious avenue that you could do some interesting concepts with them. I am curious if any one has come across a chaos converted sisters of battle army or has thought about doing one?
I have been thinking about a long conversion project of converting a sisters of battle army into followers of slaanesh. Would this be too foreign of a concept?
