[Animation swap] Spell cast animation change, question!

[WOWAW]

I have suggested to ask my question here since it somehow seems to be related to model editing.
Here's the original post I posted on the Emulation section: http://www.ownedcore.com/forums/worl...on-change.html (Spell casting animation change)

But to sum it up and to explain, I am hoping to swap the casting animation(where spells are cast my using hands) to a weapon. By this I mean e.g
Original
Fireball is being cast by hands

Requesting
Fireball is being cast my swinging a wand (normal animation where character "hits" with wand)

I know it seems a bit complicated since e.g fireball requests a casting time but those can be set to instant. I don't mind the fact that the fireball wouldn't come from the wand, but hoping that the casting animation could be a weapon animation.
If someone is interested to help me, ask and I'll explain more deeply. But if this is something that is COMPLETELY impossible, please cut my wings of hope so I can move on.
