Yes.

I think that this could be done already without too many steps.
Stop the source domain, and mount its disk image with something like:
xm shutdown source.my.flat
mkdir -p /mnt/src
mount -o loop /dev/vol/source.my.flat-disk /mnt/src
Now you can install a new image via:
xen-create-image --hostname=dest.my.flat --ip=11.22.33.44
--copy=/mnt/src --dist=sarge
The key here is to use the "--copy" installation method, which copies
a directory recursively instead of using debootstrap/rpmstrap.
(You might need to copy out "debootstrap=1" from the config file
otherwise it'llconflict and fail.)

I think that the --copy argument does exactly what you want already,
if it doesn't please elaborate.
(You might also be interested in the --tar argument which will
untar a previous tarfile of a disk image instead of using a network
copy.)
