Similar to what you're thinking but Fusion Spells (or Fusion Skills) are when two or more skills are combined to create some super powerful skill. They were an integral part in Persona 2 and I vaguely remember them being in P3 (Fes anyways). I'm thinking of implementing a Fusion Spell system when the characters get to know each other better.

I agree to this implimentation, loved fusion spells in P2
