On closer look, Omnislayer is a physiology-based power (technically Absolute Hunter Physiology), and Unrestricted Murdering is actually pretty restricted in practice (distance, speed, scale, and the various conditions of each user's specific means).

Unavertable Death on the other hand seems to already be Absolute Death Inducement in all but name (it is even classified as the opposite of Absolute Life Inducement).

So the only question left is whether or not it would work on Absolute Immortality. Rather than create a +1 power for this only purpose, it seems preferable to just leave the question open, and let each writer decide how it goes in their respective story.
