Monsterbook Boss Cards + Mu Lung Dojo = Wins?

i was thinking in ways to get impossible cards to high lvls, like pq bosses, so nexon released the exchange card in lith harbor, but is a event only and soon or later this will end. so i tought, if Mu lung dojo comes we can battle those bosses again, but they drop cards or not?

if drop, would be a permanent way to get almost all PQ bosses cards

Probably not. The monsters in the dojo are completely different if you've seen the videos. Some lower lvl bosses even seduce. I think they'll probably make them have different names, like the monsters in apq or cpq.
