Well, the character idea sounds decent, for a few reasons. This character does nothing for the majority of the game, and when she DOES do something, it is only a one time thing. Also, many Baldi's Basics characters are intended to be unhelpful in general, as they either stall the player, trick with them, or cause other negative effects on them.
As for the comic though, I will see if I can make a comic that is similar to your suggested story.
