Good idea.
Rosalina: Weight - Heavy (but a defensive one)
B - Power shield, alike to Fox/Falco B down, reflect opponents attacks. A little bigger range, so can damage opponents.
B ^ - Lumas fly you upwards for a bit.
B > You shoot lumas forward, they deal a small amount of damage.
B v - Power shield, alike Ness down B, absorbs opposing attacks. (Missiles)
Her melee attacks are kind of like Zelda's.
