I don't think that Misaki will be 10T/outcast. I have the feeling that the most beginner friendly master of a faction should remain pure (like Perdita, Seamus, Raspy, Lilith, Von Schill). So with that logic, Misaki should be pure 10T since she has the most straightforward play style, comparing to the other guys in 10T. Well, unless the last 10T master is easier then she can go dual. (We are still missing 1 10T master, right?)
Fluff-wise, isn't she the boss of the thunders in malifaux? Why would the boss infiltrate this ragtag band of mitfits? Shouldn't she, as the boss of 10T, be more concern about THE man in Malifaux(aka the guild)?
There will be a 10T/outcast and his/her play style will focus on hiring mercs or flooding the board with cheap stuff, I think.
