You can do it, just not declaratively. You'll need to leverage some dynamic visualforce

You might be able to go the Flow route

Perhaps you could create a worflow that updated the recordtype field to a new value - essentially set the opportunity to change to a different record type if the check box is checked - with a separate record type and page layout you might be able to achieve it declaratively. Not super easy, though.
