If there are reliable precommittment mechanisms for the topic, this makes it simultaneous. It still has a more complicated payout structure (publish/blackmail/bury X pay/no-pay in the blackmail case (and perhaps in the publish case, if the “victim” makes an unsolicited offer)), and different payouts for different amounts asked/offered in the blackmail box).
