Well, in my book it's still a fire/energy/magic ball, no matter how you present it.
However, one thing I had considered was a sort of 'force push' move -- same idea really, except invisible. There's a similar move in Path of Neo -- you can stop projectiles, and then other repel them (and people). It might be interesting to see how the burly brawl would work with a move like that -- shoot it, and Smiths get blasted backwards before they even get near you. It would be pretty cool if someone ran up to you, started a flying kick, and you just send them reeling backwards with a wave of your hand.
Hmm, ok, I'm slowly warming to this idea.
