Signle Wordpress theme and blogfarming

I was wondering if there is any way to make a wordpress theme unique for every blog in my blogfarm. I have one theme which I like and would like to use it on every site. I am willing to make the necessary changes to the theme so I wont get slapped by G.
Thanks

Google doesn't "see" a theme, it could look butt ugly and Google wouldn't know. Google see's code, structure and content so if you switch widgets around, have different content, turn on/off the byline, use tags on some and not on others and subtle things like that it's enough.

What will link you up more is Adsense/Analytics ID, Whois info, Hosting and IP's.
