Miles make champions and crossfit endurance or any other crossfit "program" is awful.
You can get stronger while training for endurance. But you won't break any world records, it'll take longer to get smaller gains etc. I am pretty sure a few guys around here have done some stuff like what you are talking about. Maybe Cyril?
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
