running certain servers in offline-mode

Is it by any chance possible via bungeecord or any type of plugin to set the lobby in offline-mode and certain servers that are connected to that lobby into online-mode?

For instance, a user using a cracked client can enter the lobby and enter certain servers, yet cannot enter other particular servers since they are not premium.

I really need this mechanism for my server... any ways to configure bungeecord or plugin recommendations that could be used to achieve this would be greatly...
