Heck Yeah Sounds Awesome!
Nope that's a terrible idea
As a previous advocate of Leangains who enjoys heavy lifting, I would be interested in a primal/strength mash up, albeit with a bias towards traditional weight lifting (squats, deadlifts etc) with some bodyweight conditioning thrown in for good measure.
So far I've found additional calories through regular fat intake and strategic primal carb intake (i.e. post workout) key to improving strength and providing enough energy for consistent heavy lifts.
