If Minthara is the only reason to do an evil playthrough, then maybe the evil playthrough itself is flawed, and therefore it would be a shame to lock her behind this one crazy decision which is tied to the evil path which many don't want to go but would like to have Minthara. Just let people have their apples who don't like applepie.
It's funny how the community praises mods and that everyone can play how they want (which is right) but boy do you affect their evil playthrough if they know you recruited Minthara on good terms in your own single player campaign. So better keep her away from the majority of players so few can have their pure evil experience or a funny one-time-alternative playthrough.
