I think that is a cool idea, as 'dub con' is certainly an important kink aspect where loss of control may be something a player is ok with, even as a bad ending. I would make sure that first, you make it very clear to the player that this game will involve aspects of involuntary mind control. Then secondly, make sure to include some type of 'safe word' style safety tool, like Script Change or X-Card. This gives players a means to jump in and call a stop to things if the play goes beyond their comfort zone.
Hi there!! Just putting in my two cents. "Dubcon" is shorthand for Dubious Consent. It means that consent is not clearly given or established by a character. Emphasizing here that is not clearly given by the character, it is important that consent to the situation is given to the GM by the Player controlling the character.
Once proper safety tools are established, and everyone is OK with mental corruption and characters getting into situations that may involve Dubcon, then it's all good!
