Just be careful to make sure the penalties are accepted. How would you handle the situation below?

The game is tied late in the 4th Q and Team A with the ball on the B10 decide to kick a field goal. The kick is blocked by team B. The ball is recovered by B6 who runs the ball to the A10 before he is tackled. Team A had an illegal formation at the snap. During the run back team B blocked below the waist at the A5. Time expired during the play.

Lessee if my memory of NFHS is any good:
B: accept penalty, A will retain possession and gain another down. Or B  declines the Illegal formation to retain possession. and nullify the offsetting penalties and replaying of down.
A: accept penalty BBW applied at A5, B allowed a down, or decline the BBW to kill the clock.
Both sides will decline penalties. Game over.

Isn't "last timed down" a NF term?  I don't think it has the same meaning as "down in which time expired", which is NCAA-specific.

BTW, the correct term is offsetting fouls, not penalties.
