If you don't want to wait then why not create another character on a low population server? Additionally forcing new players to create characters on other servers is not the right thing to do. I'd be pretty disappointed if I was psyched up to play with some friends only to find out I couldn't join their server and guild because the server was locked.
Not to sound too condescending but your argument comes across as a "not in my backyard" type of thing. If you're sick of waiting, then don't... join another server as you would have a new player do. I'm not saying leave your other server, just keep your options open.
