Legal or not?

I would say legal, as long as both A77 and the QB are set for a second before the snap.

Not only legal, but common practice. You might have a judgement to make about "simulated" 3 point stance in cases where the TE set and the T started to make a move in sync with the TE to get down to 3 pt. I would look at it lineman by lineman, in isolation, judging only whether each individual's move got him into a 3 pt., not whether it looked as if he was going to get into it.

More interesting is whether after the T's shift, the TE, who is as close to the ball as before but now farther from the nearest teammate on the line, is allowed to shift out of 3 pt. I don't know the current provisions on false starts in all the codes regarding ends.
