I would love to see this level of realism but I don't think it would be that necessary. However, what would be a nice idea is if the Ride OPs worked on the same basis as the other park workers in terms of mood and satisfaction i.e. If they are happy, they'll work as fast as possible (maybe even at a slightly unrealistic rate as some sort of game reward. It is a game after all!) and get people on and off as fast as possible and do all safety checks with speed and precision, where as if they are demotivated, unhappy, sad etc... They could work at a slower pace and perhaps not be as effective or safe by by forgetting to check a restraint here and there, not caring about the height of riders and let a few smaller people on and generally start decreasing the efficiency of the ride and how many guests they get through per hour.
It could even have more dire consequences for you as a park manager. Perhaps the poor work would leave the inspector (assuming they'll some sort of inspector) very dissatisfied and incur fines for not being safe.
