Perhaps go with the 2nd idea of setting up an alternate website.
I’d be careful with that. Still seems like trying to cheat the Google system.
From a recent post on NETTUTS:
"Google is very strict about duplicate content and severely penalizes sites which do so. This is regardless of whether the content is on different domains. If the same, exact content appears on different pages, the page last indexed is going to be penalized."
Aye, you’ll most likely have to apply for reconsideration. Even then, it’s a 6 month wait.
