There are/were other select few mixing Fila with game pit bulls. The outcome was an even more intense dog than the Fila due to strong qualities of both dogs and hybrid vigor. The outcome in terms of type some of the first generation litter looked exactly like a Fila and some looked like a taller and heavier pit bull. I'd imagine the best qualities of the Cane Corso and Fila in your breeding would create a very athletic with strong ojeriza toward strangers.
