I can imagine they would! While they’re studying different things (Susanna studies aquatic pokémon biology while Edmond studies the art history of legendary and mythical pokémon), they’ll often help each other out if they’re both at the Magnolia labs. Edmond looks up to Susanna in a similar way to how he looks up to Sonia and Susanna in turn doesn’t mind sparing some of her free time to lend him a hand if he needs some help. I think in some ways, Susanna would remind Edmond a bit of his uncle Alain in terms of her personality, so there’s another reason he’d get along well with her.
