I'm a huge fan and love Monkey Island, but I feel that you are setting up a scenario that will never happen by demanding to own the IP of Monkey Island.  Lately Disney has been giving the LucasArts back catalogue far more attention than latter day LucasArts ever did.  If Disney allowed you to make your own Monkey Island 3 with full creative control and "final cut" rights, would you consider it?  I would love to see your true vision of how Monkey Island was supposed to end.  I need to know the true secret of Monkey Island before I die.  It's on my bucket list.
