I doubt it; I honestly thought they had different names for a while (back when Bloodlines was new, and I hadn't played Redemption in a while). I thought one was "Mercurio" and the other "Mercutio" (as in, Romeo and Juliet). It's probably just a coincedence.
I can see why they might've chosen "Mercurio" for Bloodlines - Mercurio being the Italian or Latin or something for Mercury, the God of Travel, Messengers, and Thieves. Bloodlines Mercurio certainly seemed to fit neatly into the intermediary/criminal aspect of the god. (I bet he wish he had winged sandals after getting that beating, though.) I can't see any similarities between the Redemption Mercurio and Bloodlines Mercurio.
