Not really. Asides from there being no evidence to suggest that Cang Du is stronger than Harribel to begin with, Hitsugaya has been training for more than 17 months since that battle. Presumably he now has full control over the power that he only very reluctantly used to end the stalemate he had with Harribel.

While I somewhat hope that Cang Du isn't down for the count since I'm a fan of his character design, he is almost certainly beaten now, if not dead.
