As for her being overly ambitious, nothing wrong with that and I think a branch route for her where as she stated, having Alessa on her knees under her....could end up being a very interesting path....if it happens. I think it could though, as yes, it requires two distinct flags to get that conversation. She has already been promoted to a full T1 romance (from her previous lesser T2 route) and you will only get that as a dom. So really, it's not that much of a branch when you think about it, still the exact same dom route for Kane, the only difference would be a slightly different 'romance' (or torture depending on points) where you're still bad ass aiming for the top but defer to her sexually instead on the SS path rather than being on her normal T1 romance path.
