Yes, we did it on KBCW. I dug up my old screens and I have 80% book damage, cause I abandoned the 1 BD challenge on lvl 43 and switched to 1 stack of Black Knights + Eviln. Well, Call of Nature and Demon Portal weren't working the same way as they do in KBDS now. I don't even recall using them so extensively, cause they did not provide sufficient amount of troops - and the ones you got could only survive a few hits, so you were much better using Gift + Paladins than wasting so much mana on Call of Nature, for example.
