Dead hand is dead. Rare exceptions can be made (e.g., errant dealer muck where cards are clearly identifiable), but a novelty rule that overrides this for the lulz is a silly gamble against the patience of your players. All it takes is one player to get sore about being stacked by a dead hand.
That said, it is a novelty rule, and if you have the same set of players all the time and they like it, good for them. But it's starkly at odds with basically every poker rule set in existence. Probably even more egregious than letting someone go south or add to his stack mid-hand.
As you can see in the replies, most players bristle at this; your chances of being able to recruit players into your game who will be happy about this rule are slim. If you do bring new people into the game, you'd better be crystal-clear about what this rule means. I know if I sat down to a game for the first time, if this hasn't been well-explained to me and is suddenly invoked in the middle of a hand I'm in, I will feel like I'm being swindled or toyed with.
