In a Naruto - Digimon fanfiction, Sakura could team up with a healing - type Digimon. For example, a Gatomon could help her in her medical ninja skills.

Another aspect could be the jutsu in Naruto's world interacting with the demonic powers in Devilman's world, creating some unique and unexpected battles.
