Extended story would be great. Animal orbs with chance to proc effects upon melee/ranged weapon strike, or upon magic strike, possible stat penalties as a trade-off. Possibly animal orbs with purely cosmetic effects, whether they be applied to parts of your character, your character as a whole, your sandwich'd character, or even your projectiles.
A mini painter character could be fun. Magic could be a wave of paint for Y, wad of paint or a paintbrush for B, and so on.
The wizard minions could be fun, but it might look kinda goofy with them flying through the air with an axe, tearing enemies a new one without touching a spell.
*shrugs* That's all I got.
