Well, sort of. The movie doesn't really have a traditional 'pitch black love story' but there are some dark and intense emotional connections between the characters. They are all so different and they have to learn to work together. This process involves a lot of friction and then gradually some form of deep bond, which can be seen as a deviation from the normal love story concept and has some 'pitch black' aspects to it.
The idea of good vs. evil is present in both. In Rise of the Guardians, it's the Guardians against Pitch Black. In Frozen, it's Elsa against her own fears which can be seen as an internal evil. In fanfiction, the Guardians could help Elsa face her fears. Jack Frost could use his carefree nature to show Elsa that she doesn't need to be so afraid. And the Frozen characters could help the Guardians in their fight against Pitch by bringing their own unique skills and determination.
Some fanfictions might take a different turn and introduce new threats to the guardians. Picture a story where a powerful dark force from another dimension comes to their world. The guardians then have to find new powers within themselves and work together in ways they haven't before to defeat this new enemy.
