If you’re up for experimentation I think I can get you started.
There is a TestReanimate spell in the CS that uses the same effect ‘reanimate’ as the staff enchantment EnStaffReanimate.
You will need to make a new unique Spell and Magic Effect.
In the CSCreate new spell;
rename ID and name to something like MyReanimate or Reanimate2. You may want to check PC start spell to give your PC the spell right away.
Create a new magic effect;
rename Name to MyReanimate or Reanimate2. Check the Spellmaking box.
Click Save and save with new name as an esp.
OK
Now if you feel really lucky and you have the DLC create a Tome with the spell and place it somewhere in the game world.
