This is a bit outside my field. That said I don't think so.

The overall crystal should be very weakly magnetic. You want strong magnet with a high flux density so the electric field can push or pull against it.

I think this would be more useful in quantum computing as you get two bits polarity and spin. Or high density storage.

But who knows. There are clever physicists out there that know a lot more about this. They presumably see many more possibilities then I do. If the effect can be interrupted you could stitch between states. Like turning a magnet on and off. That would have uses like you described.
