The problem with doing anything in a sim is the training center can only do what they have approved course syllabuses for. In theory you could do a VFR commercial type rating in a sim but I doubt any training center has a course for it. I'm thinking the "aerobatic maneuvers" Climb references are the chandelles and Lazy 8s but they are only required for a SE commercial. There is also the requirement to hold a FAA PVT to qualify for a commercial. You could get a 61.75 "based on" PVT but it's another hoop to jump through.
