Gunblade script+Cloud pose?

Okay, this may get a little complicated. I'm using the Judgement Gunblade from Schism Industries. But, I don't like the way I hold it when I unsheath it. Is there any way to alter the script so that my avatar takes the "Cloud Strife fighting pose" instead? I know some swords have a script that does that...

BTW, I'm an amateur scripter, so you may have to explain any techinical details.

The ability to do this depends on several factors.

1) Do you have modify rights to the script?
2) Does the gunblade have the animation in its inventory?
3) How does the gunblade work with the animation? Does the position of the object change when you unsheathe the sword?

First off, if you don't have modify rights to the script, you will be limited to what you can do. But more importantly, how does the gunblade access the old animation? If the animation is stored in the object's inventory, then you can trick the script into using your new cloud stance. This is done removing the old animation and putting the new one in its place. Just make sure it's named exactly the same as the old animation. Also be sure you put it in the same prim as the old one was.

If you look at every prim's contents and can not find the old animation anywhere, then you are out of luck. The script is accessing the animation by a hard coded asset ID. The only way to change it would be to modify the script (and that means you need to have the permissions to do it).
