Hot Rod Cameras President Illya Friedman debutes his new PL mount Canon 7D. Hot Rod Cameras will convert your 7D for just over three grand. You can get a brand spanking new Hot Rod Cameras PL Mount 7D for around 5K. Illya has removed the mirror and replaced it with a sensor gate for protection. The prototype I checked out at Createsphere 2010 looked rock solid to me. This modification should work with other Canon EOS cameras as well.
