I doubt this is a serious thread, but just in case, this would make the queue much worse rather than better. The queue is huge because everyone is trying to get on at once, not because the server is "full" and can't let any more people in. If people got kicked out more frequently, then there would be even more people trying to log in all at once.
30 minutes is a great medium amount of time that keeps the servers from actually filling up with people who are truly not playing while also keeping people who are just grabbing something to eat or going to the bathroom from clogging up the queue itself.
