Only if you do the virtual-to-physical translation
exactly at the point when the relevant process is
in memory and when the memory is swapped in and not
out on disk, and you don't let the guest run between
the point when you do the translation and when you use
it. (Otherwise windows could swap something out or
change to a different process.) But if it worked to
do that then the 'x' command would work too.
