Atleast a Daedra Heart has a far more similar structure to a Human Heart to that of a Briar. Briars are just a seed of a plant, they don't look like they can pump blood. Do the Briarhearts even got blood flowing through their arteries still?

Having a Daedra heart in a Briarheart would be like how the Numidium was powered by the Heart of Lorkhan.

When Neloth in Solstheim says "It puts their lifespark in direct connection to the natural forces". Instead of having a direct connection to natural forces, they would have a direct connection to the depths of Oblivion, and have the ability to summon extremely powerful Daedra.
