Thats hard to say. A lesser Mojave Butter should be a BEL, and some of its offspring should be too. A Black Pastel Cinny Sable should be a solid black snake, and the offspring it produces should be solid black as well. Its basically the same question as "What would a Super Lesser Super Black Pastel look like?"

A very interesting question it is, but unfortunately no answer for it yet, only theories..
