That's fair.  One could also argue that eating a god eater at least temporarily gives one the same abilities.  But even then, in the long term, that's still likely to end up with one very dead revenant.  

At least if healing bullets work on revenants, they won't have to worry about dying quite as often.  Transfer bullets and burst effects might be a little less useful, though.  The real fun of this sort of thing would be doing stuff that doesn't happen in the games but still makes sense, though.  God Arcs are mini Aragami, so you can probably use them to cut (or devour) a way through walls and other normal matter, for instance.
