That's precisely what a fully-realized Continuum experience would be. Using the latest Windows on ARM with x86 emulation and the Composable Shell (CShell) [1] would give you a great experience. Note that the Lumia 950 with the current production of Continuum is effectively a technology demo of that model since it doesn't have x86 emulation [2] and therefore can't run the full breadth of Windows applications. That said, Continuum already does use the Phone's display as a keyboard, mouse, or just a second display according to your preference.
