I think this is a really original and creative idea. I do have to agree with the poster that said you have to at least give this thing a chance. Do you want to make this a legit RDWHAHB experiment, where you're intentionally making some common beginner mistakes but still hoping to turn out a decent beer, or are you just trying to see how disgusting you can make a batch? I think the mistakes you need to incorporate are the ones that are commonly made, but unless things go horribly wrong, will usually still result in the beer being okay. Don't include some of the mistakes that have a 90% chance of completely destroying your beer, with a slight possibility that it might be okay.
For example, mash hot, but still at a temp you know will convert. Don't mash at a temp you know will kill all the enzymes. Don't sanitize your equipment, but don't use completely soiled, moldy stuff either. A beginner can forget to sanitize this or that, but even the complete noobs won't put their beer in a bucket with mud and hairballs in it.
