By whom? An SSC?
As far as the rest, I'm not sure I see a question but it sounds like you may be wondering if you can DL more while you're not squatting. Is that correct? The answer is very likely yes, and it's probably worth a shot. If you were just doing one heavy set of 5 per week, keep doing that and on the other day, do something like two sets of five at ~80% of the heavy day's weight and tack them up from there.
