Instantly? After contending with Malgus and surviving? No, I agree.
As well as her showing the ability to divide her attention against pressure-oriented duelists like Malgus and Grievous to utilize TK as in the "Hope" trailer. Though someone could argue Grievous outstrips Malgus enough in this to stop her from doing such.
Nah, you really can't with Grievous
She sends his ass flying with a casual TK blast per Malgus (hey, if scrub season 1/2 Ahsoka Tano can block his strikes, not exactly like his metal carapice offers him dominating strength. Can his be greater? Sure, but the disparity would hilariously negligible) keeps his ass pinned if she needs to "charge", and crushes/shreds him to scrap
