You could make your own interface MyQueue with all the methods that Queue has minus the remove method and use that. You could give the MyQueue interface a Queue toQueue() method that returns the object converted into a queue.
This conversion process could involve just returning a new instance of an anonymous Queue, which, for each method X, would simply call/return this.[X]. For the remove method you'd call this.remove() but then return a boolean rather than the return value of the this.remove() call.
