Depending on whether you use any applications which have dependencies on
systemd, you can certainly run Debian Jessie without systemd. It uses systemd
by default, but it's trivial to remove and replace with sysvinit, provided you
haven't installed anything which requires systemd. If you're starting from
Devuan, this is unlikely to be the case...

I've never tried migrating a Devuan Jessie system to Debian Jessie, but I have
done it the other way around, and this is what the dist-upgrade part did for
me:

# apt-get dist-upgrade
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Calculating upgrade... Done
The following packages will be REMOVED:
  systemd-sysv
The following NEW packages will be installed:
  e2fsprogs init libfdisk1 libss2 sysvinit-core
The following packages will be upgraded:
  base-files bsdutils debian-archive-keyring init-system-helpers initscripts 
libblkid1 libmount1 libsmartcols1 libuuid1 lsb-base lsb-release mount sysv-rc 
sysvinit-utils util-linux uuid-runtime
16 upgraded, 5 newly installed, 1 to remove and 0 not upgraded.

So, only 5 new packages got installed, and 16 upgraded.

It seems reasonable to me to assume that much the same would be the case for a
Devuan Jessie -> Debian Jessie "upgrade". I'd say it's certainly worth a
backup and a try.
