M.D.M. was in the right here; there's no way that would have worked. Let me point out three problems: 1. All Marines of Vice-Admiral rank or higher are proficient in Haki. 2. Marco had no way of getting the key to Ace's handcuffs. 3. As soon as Ace was freed, Whitebeard planned to use his powers to sink all of Marineford, prompting all his crew to run away, prompting Akainu to do what he did to kill Ace.
