Teams policy to limit user meeting access to certain number of members from specific group

[KConing333]

I have a scenario that I need some assistance figuring out. 
We have a group of 7 individuals within our organization. These individuals are not allowed to have more than 50% of them in any one given place without previously scheduled meetings and agendas, physically or digitally. 

I need to configure a way that will not allow more than 3 of those individuals to be in the same Teams meeting together. Is it possible to create a policy to do this?

Only thing I can think of is Information barriers. Have a look https://docs.microsoft.com/en-us/microsoftteams/information-barriers-in-teams
