She can't turn heel, there are not enough credible baby faces right now. They just turned Asuka heel, doing the same with Bianca would be stupid right now. I can however see them ramping up her aggression more. More of a no-nonsense type of attitude of "I'm not gonna take this crap anymore" type of approach.
People might have been cheering Chuck in that Asuka segment but we all know Chuck baby face runs never work out. She always goes back to being a heel sooner or later and it's what she prefers.
