The idea is to play it similar to the Diablo 2 Necromancer, just let the bodies hit the floor, I mean explode.

I think it will have a good clearspeed, but will have problems to kill bosses, something I would be fine with.

It would look along the lines of following PoB:

Create the first corpses with desecrate totem (to also use the Maurauder Ascendency), the scorch them with scroching ray while let them explode even more with infernal cry.
