My local strongman gym is my garage, haha. I feel like I'm the only strongman on central coast CA sometimes.
I truthfully think the deadlift proper is a pretty crummy exercise for size and strength. If I were to run this program, I'd keep the lower body day entirely squat focused for the ME movement (alternating things like squats, front squats, safety squat bar squats, box squats, etc) and work on my hip hinging as bodybuilding work. On your upper body days, I'd have a mat/rack pull in place of the shrugs to develop the upperback AND the pulling mechanics of the deadlift, and I'd just keep hammering the upper back otherwise. That should still build a strong deadlift AND a strong squat/lower body.
Training only 3 days a week really kind of limits things, but it could still work.
