Animation Questions (2)

Not sure if this is the correct forum, so here goes:

1. Is it possible to just rename existing animations and make them work differently? I.e, I want a custom model's "Spell" animation to be just another "Attack" animation; can I go into the sequence manager (or whatever) of Magos and rename it "Attack - 3", and it'll work (1/3 of the time) for his attacks?
As another example, I want to switch a unit's "Walk" and "Walk Fast" animation, because they don't match the name. I don't know if this would be any different from the above example, but meh.

2. I read Callahan's tutorial on "Changing a Decay anim to a Dissipate anim -> Hero", and I was wondering; is it possible to do the reverse? Is it just doing the tutorial backwards, or is it more complicated than that?

Any help would be appreciated, especially for the first question.

1. Yes, you can; people juggle such things all the time.

2. No reason why not; you'd be making it fall into the ground instead of rise into the air, though you'd need to add an extra corpse, extend the length of the decay to 60 seconds, double it to get decay bone and decay flesh... Not so easy, but anything is possible.

Awexome. Thanks a lot.
