Not possible
Moving the location of static positioned elements would be possible in theory, but it would be far from "drag&drop" since the hack would need to rewrite some of the render calls to draw at a different position.
Adding support for dual screen or exporting ingame windows to "Windows" windows is completely impossible to achieve with any type of "simple" hack.
If you want such features, there is only one way to get them: Annoy Anet-employees. No one on this forum can help you with such complex things.
