There could be girls that are disowned princess commoners that go magic apeshit, but they would also have less power than their grandmother.

I like the idea that she basically used force to be the queen, though, she probably would have assassination attempts on her a lot.

She didn't use force per se to reassert herself. She just basically tagged along her beloved and happened to destroy who threatened him. Retainers probably stood a few steps back when they realized who they were trying to bully.

The assasination attempts were the reason why she left once she made sure her children (the King and Regent) were properly raised.
