Those jackstands are similar to what most of us use - it doesn't change the equation. I do it all the time, but I place the stands under crossmembers or such to avoid marring the finish. I also leave the floor jack securely positioned at the end of the vehicle where my body is, and maneuver around it as needed. If an earthquake hits, though, I get religion fast!
