I didn't think I would have to defend doing a simple operation that is safe, efficient, and fairly inexpensive. Yes you probably could use car drums but would have to further machine the hub to fit the center hole. If you look at the quality of the Chinese made parts out there I would prefer to use a good and serviceable old part. The drum is centered by a hub flange and studs. Everything is held in place by lug nuts and the wheel the same as stock. It is no more at risk of spinning out and breaking than a stock drum. The machine shop that did the work on the axles and drums specialized in off road vehicles. He does them on a regular basis and has had no problems. Off road stuff certainly gets more severe use than one of these trucks. I guess you could go to Currie and have some new axles made. I'm sure they could accommodate you.
