Delay before special attacks

Hello

Is it possible to make that some attacks have a delay before they actually cast. Let's say I choose Fire with Terra so her animation of casting will last 2 secondes before the actual magic is casted (the ATB is still running while the delay occures). If I choose, let's say, Ultima it could takes 10 secondes before casting.

I think it was like that in FF4 if I remember. Also, it's kind of different but FF Tactics do this a lot.

And if it's possible for Magics, I presume it should be as well for skills like Pummel or Autocrossbow.

I want this to tweak some OP attacks and give Edgar/Cyan/Sabin/Shadow a real reason to use their Fight commands.

Thanks ! 0:-)
