I do the elevated dead lifts in 4DS. I don't bother to take my step height down. I just step up and do the dead lifts on my tall step. For me, I've found it's a mental thing to do them elevated rather than on the floor. I go down farther when elevated, even though I'm not going below the level of the step. Also, when my toes are hanging slightly over the side of the step, I really put the weight in my heels where it should be.
