That wouldn't hurt, but it is no way needed. Grain bill as OP listed is pretty much a Guinness clone, with the addition of cara pils and crystal. Has 1# roast barley according to his recipe... that's correct, beer SHOULD be black.
Agreed. You can go with more dark grains but I've done stouts with 1 lb of roasted barley or 1 lb total roasted barley plus chocolate and they were very dark, and that's without the Amber LME or darker crystal. As I mentioned before these were partial mash but my software says extract with steeping should be same color.
