Deltarune x Aftg crossover

Watching Chapter Five of Deltarune, and it got me thinking who the Neapolitan (Andrew/Neil/Francis ship name) would be! This is all subject to change.
Andrew could be Susie because both are seen as intimidating; Susie's a monster, which parallels with Andrew and his group being dubbed The Monster(s). He could also be Kris with his mysterious, closed-off demeanor, penchant for trouble, and protectiveness over his loved ones. Neil seems like Kris as well, with his identity and autonomy issues, shared demeanor, mischief streak, and protectiveness. I'm leaning towards Susie for Andrew and Kris for Neil, for now. Mostly because of everyone's perception of Andrew being this Monster figure.
Noelle would be Francis. Both are deer-themed, have difficult families, struggle with identity, standing up for themselves, and are in love with someone everyone thinks isn't good for them. Also, because Francis is my self-insert, he also loves horror! Just like Noelle. I don't think he'd be an excellent student, though, average in everything except for classes he cares about/will help his career path in psychology.
