Is it possible to convert a hybrid into a PHEV?

In a recent reply to a question you recommended a Lexus NX200 Hybrid as a good reliable car but I think I noticed that this is not a plug in hybrid. I was wondering if it is possible/economic to convert a non-plug in to a plug in? I am thinking along these lines as I drive across Europe to Sweden each spring and return each autumn and the ability to charge from the mains would be a significant advantage.

No - it wouldn't be an economical optional. You'd be better buying a plug-in hybrid in the first instance. Consider a Mitsubishi Outlander PHEV.
