[Request] Creating a recipe for the Polly Waffle

So the Polly Waffle is an Australian chocolate bar that wasn't being eaten until it was discontinued in 2009, now everybody wants to get their hands on it. I do as well, but they don't exist anywhere anymore.

So, why not make it myself? Well, no recipe exists that I can find, so I have to start from scratch.

Here is an image of the middle of the Polly Waffle. It's described as "a waffle wafer tube filled with marshmallow and coated in compound chocolate". Now I daresay that "wafer tube" is similar to a wafer stick, hollowed out, and either stuffed with marshmallow, or, more likely, made and allowed to set around a shaped marshmallow. I'd say it is then dipped in chocolate.

Does anyone have any idea how i can go about creating a recipe? How difficult would it be to make the marshmallow, shape it into a tube, cover it in wafer, then dunk in chocolate?
