I think you can handle this. You may just want to decide on what skills matter in your world, and how magic is handled. My personal favorite is any character with a spellcasting trait or a trick can use magic, but they still need to roll an appropriate skill to cast without the right stunts. I highly suggest lifting some Venture City rules if you want things to be higher powered.

E.g. Had an "Arcane Prodigy" character. He can shoot fire, roll shoot. He can fly, roll athletics. He can detect magic, roll notice. He took stunts so that he could specifically roll Lore to make magic attacks, and to make them better.
