Giant waste of energy that will reduce output on the deadlifts. Instead, as the first exercise of the heavy lifting, do cleans for 3-5x1-3, working up to a weight close to what you’d start deadlifting (if possible). That will serve dual purpose to work the cleans and warm-up the deadlift, basically mechanical advantage work. Also… deadlift x 20 reps? No.
I don’t even know what that set/rep scheme would accomplish. Sort of cluster reps but not really. Power cleaning each front squat from the floor or from the hang would be a much simpler solution.
The other obvious option is to stick to the plan as the article described and just hit power cleans on the “bonus day” followed by little else. Go in, hit the exercise hard, leave.
In any case, neither approach you wrote holds anywhere close to the idea of the Mass Made Simple plan or 5/3/1. You can give it a shot your way if you really want to or do it the way the wise old coaches planned it.
Also, if you’re doing cleans as part of the heavy lifting, I’d avoid them in the complexes, otherwise you’re doing cleans twice per workout twice a week and turning the plan into some kind of funky power clean specialization routine.
