I never do lunges. I do squats and box squats. I do Zercher squats in place of Front squats.
Currently, the workout I'm performing is the one I have listed above. I do work with Dumbells, but it's only minimal work. The majority of my workout takes place inside a power rack
WRT To sled, I do typical GPP sled work with nothing more than some ropes and a couple of 45lb plates
