I suppose it is possible but no extant VM software currently doesn't. It isn't as simple as killing X. The graphics card in the machine also displays the console. The state of the console would have to be preserved and restored by such a workaround. You'd probably want to extended guest tools since this would also put one out of touch with the host operating system. Also, the graphics card is still going to have PCI address space and registers reserved for it by the kernel whether it is in use or not. Any VM that wants to directly control host hardware has to have software written to deal with that as well. The guest would also have much more access to the host than VM software usually gives and that is a primary reason for reluctance to implement such things.
