Nami could learn to trust more deeply, and Luffy could become more aware of his own emotions.

The element of discovery is key. Imagine Luffy and Nami find a lemon - colored Devil Fruit. This would create a whole new set of possibilities. Nami could use her wits to figure out what kind of powers it might have, while Luffy would be more interested in just having it.
