These guys don't think so.

My perspective is that "Claymore" that focused on these guys is ending. Perhaps a new series will start up that takes on a new protagonist in the major war that's going on, with the Claymore characters joining in later as some side/secondary characters.
That, or like Y/DBZ reckons, they're having a sequel. The change of name can indicate that the girls no longer call themselves Claymores (not that they ever really did, but they refuse to be acknowledged as such now?)
Random parasite coming out of Descendents of Dragons is kinda... eh?
So these dragon fellows can irreversibly transform. (I can't remember if they lose their minds when they do).
Mixing the flesh of a transformed and original DoD yields a parasite that lives through (and feeds on) humans.
Claymores are made by inserting Youma flesh into the girls... so does this flesh actually contain any parts or consciousness of the parasite? You re-establish the urge to eat humans after you awaken, but that's only after you reach a threshold.. before which you can still benefit from an increase in power without disastrous side effects (until you reach 80% output - after which the output involuntarily rises until the 100% awakening threshold).
The Youma thing is easy enough to deal with if you just swallow it.. but the creation of Claymores themselves based on that same concept is pretty muddy still.
