I have mixed feelings about how effective this approach could be, especially in younger populations that don't have the best grasp on what is happening and where the boundaries are in terms of playing together or interacting. I hate to say it but I think it's all or nothing, either no one goes in or everyone goes in. Even if a smaller portion of people get sick, they still have the option of spreading it..especially if they don't work remotely which many people can't.
