I want to add to this that I tried the following:

 - Install a wheezy system with debootstrap in a chroot
 - Change the source.list to jessie
 - Install sysvinit-core from jessie
 - Dist-upgrade the chroot to jessie
 - Try to install the systemd-sysv package

The extra dependencies being pulled are (with the recommends):

root@fornost:/# apt-get install systemd-sysv
Reading package lists... Done

The following extra packages will be installed:
  acl dbus dmsetup libcap-ng0 libcryptsetup4 libdbus-1-3 libdevmapper1.02.1 libexpat1 libpam-systemd systemd
Suggested packages:
  dbus-x11 systemd-ui
The following packages will be REMOVED:
  sysvinit-core
The following NEW packages will be installed:
  acl dbus dmsetup libcap-ng0 libcryptsetup4 libdbus-1-3 libdevmapper1.02.1 libexpat1 libpam-systemd systemd systemd-sysv

As you can see the number of new dependencies being pulled are minimal.
