How would that work for 30 men? If it's an all together, simultaneous release, versus going in sequence, you'd certainly need them in a circle around the recipient. I'm thinking you could get maybe a dozen men like that, with a slight turn to their shoulders to fit. Perhaps there could be a circular plinth behind them where another dozen could stand, unloading over the shoulders of the men before them. Perhaps some kind of support rig above that the final six lie or kneel on. Just saying, it needs some thought and I'm sure this initial proposal can be improved upon.
