No one really knows if Belle's attempted kiss would have worked. Both Regina and Belle thought it would. So did Rumpelstiltskin. But since Belle never kissed him, we don't really know if a Twu Luv's kiss would have broken the curse. Best guess: TLK can break the curse (provided the DO is willing to accept that love), but the Darkness would be freed from the dagger and target someone like it did with the Hat. It would only shift the problem, not solve it.

Side note, I hope Belle and/or Regina tell Hook and he tries and fails on Emma, so the writers would have the mother of all chances to explain how it only worked in Skin-Deep, if it did at all, but never afterwards. But I'm afraid I'll be shelving this on the LOST Potential cabinet.
