Yeah, I think the idea of making sunrise from the trail head is crazy, too. But I put the info out there if they were crazy enough to want to try.
7 hours is certainly doable for someone in good aerobic shape, but they'd need to limit breaks to 5 minutes per hour or so, and hustle on the trail.
If I were crazy enough to do that, I'd plan on taking one or two naps by the trail on the way down.
Jeffsd: since you have two days to acclimate, you might consider this: Saturday AM, drop into the Visitor Center in Lone Pine to pick up your Monday permit, and while you're there, ask about a walk-in day hike permit for THAT day (Saturday). If any is available, you could day hike the trail -- maybe all the way to Trail Camp on Saturday and return, as a training hike. That would give you a huge advantage to familiarize yourselves with the trail that you would be hiking through the night.
