Question about Battle Models

[Sapphire]

Hi all!

A bit of a weird question, I tried it myself but it crashed on startup pretty much. I'm wanting to know if it's possible to change Clouds battle model to the Dragon, Nibel Dragon/Glacier Dragon or the Dark Dragon. I tried myself by simply changing all of the RT** files to that of the Dragon files, this however crashes the game.

Just wondering if it's possible and if it is, could someone please steer me in the right directions?

Thanks,
Sapphire

EDIT :

I have MILD success, sometimes I get this far and it crashes, sometimes it doesn't even load the battle and crashes.

EDIT 2 :

A bit more success now, for some reason though there's bits and pieces missing from my dragon... And the wrong animation is playing when I cast flame thrower..

You can't substitute that easily, for multiple reasons.

The number of bones might be different.

The number of "body animations" might be different. (Different characters have different animations for stand, lunge, drink potion, use magic, etc.)

The number of "weapon animations" might be different. (Each character can have different weapons, each with separate animations.)
