What are some ideas for a sequel(or prequel!) for Princess and the Pauper?

Sequel Idea: Preminger escapes jail, or he has a son that seeks revenge against Anneliese and Erika, the girls switch places, something happens to Dominick...(Anneliese and Julian finally sing a song together!)

Prequel idea: How did the king die, how did Preminger(a peasent's son) get to be the Queen's advisor, how did Anneliese and Julian meet, what happened to Erika's parents, what happend to Dominick's parents, when Anneliese and Julian fell in love was it love at first sight, or did thier love gradually grow and become stronger?

Or .....

Preminger escapes from a prison and appeals to his friend, bad wizard. Preminger wants, so this wizard concluded Anneliese in the music box. Wizard appears in the palace, but instead of Anneliese concludes Erika in a music box. Dominic, Anneliese and Julian searching tool, which can release Erika ...
The idea of a prequel is also good.

Or ...


-Preminger escapes jail
