I think an addition that would be fun would be a police escort, where you and other officers have to protect valuable cargo get to its destination, such as guarding oil wagons and armoured wagons from outlaws and raiders or escort a most wanted criminal to the appropriate jail for jailing, execution or whatever sentencing can be added to it.
All for thought, I appreciate some of the of the ideas I've put forward may seem quite the task, but here's hoping😉
