How to Simulate Polymorphic Methods

I would like to be able to do something like the following:

&myCustomClass.CustomMethod(1, 2, 3);

&myCustomClass.CustomMethod(1, 2);

and have PeopleTools route the calls to methods with different signatures, i.e., polymorphism. I know PeopleTools doesn't support this natively. Has anyone come up with a clever way to simulate it? Off the top of my head, I can think of 2, but they're clunky and inelegant

1. create one method that accepts an array, then have it delegate to sub-methods based on the number/type of elements
2. write the entire class in Java
