I think you would either have to create a custom List (implementing the List interface) or a custom Iterator. For example:

ArrayList targetList = new ArrayList();
ConvertingIterator iterator = new ConvertingIterator(targetList);
// and here you would have to use a custom List implementation as a source List
// using the Iterator created above

But I doubt that this approach would save you much.
