I think it is, but depending on your comfort level with risk, I'd probably try to leave the lounge by 6:30. With pre-check (assuming it's open that early), security shouldn't be too bad at that hour, but keep in mind that it's a bit of a long walk. I haven't had any problem getting into the opposite airside, but I've used mobile boarding passes each time.
