that content of your sister sites should be unique as now Google is very strict on content.
That's a bold statement with all the duplicated scraper crap that abounds currently on the Net.
Theoretically it should be possible to have identical sites in each country since Google supposedly ranks geographically by country code tld. Whether this is true or not is very difficult to prove however this last year I uploaded my example.com to my example.co.uk simply because Google removed my .com from their .co.uk SERPs.
All I can say is that the site is fully indexed and many pages are now ranking where the .com used to be.
I'm not guaranteeing anything other than why not try it out?
