I'm not sure. The character had specific powers and they could be revelent to the story. I don't know. But you can't just give these powers to an Assassin. So I'm not saying it impossible, but there's no real evidence of it, except for the concept art in Black Flag, which might have just been an easter egg to the cancelled game, rather than a hint for a possible future one.
