Dude,
The whole point of homebrewing is to brew something that tastes good.
Why bother assing about trying to clone WED when you can buy it for feck all at the bottlo?
By the time you buy the ingredients, and factor in a few hours or screwing around, you will have spent more than the carton of piss would have in the first place.
I think alot of people in Australia undervalue their time, and sheesh, 10 hours spent trying to re create a crap beer for scratch, seems like either some truly false economy, or fanaticism.
But if you have time to waste, be my guest.
