Yes, it's definitely moddable. In Momentum 2 I had them arrive without afflictions, as commanders, and without shattered soul.

I also let specific types of tarts be summoned, but I wouldn't do that again. I agree that part of the fun is not knowing what type you'll get and, as Psycho pointed out in that game, only a few types would get summoned if there's a choice.
