Pit's Final Smash Centurion replacement

[Runefactory]

Hi, I'm currently working on changing Pit's final smash.
I've already edited the background and I want to replace the centurions(angels?) with the model of Ike's sword.
I've replaced the WpnPitIkaros MDL0 file with WpnIkeSword MDL0 and changed the textures to Fit_IkeBlade, Fit_Ike07, Fit_Ike01 and metal00.  However when I use the Final Smash it causes the game to freeze and make the annoying beep sound.  Can anyone help me with how to replace the Centurions/angels?

I'm guessing it freezes due to the fact that Ike's sword has less bones than the Centurion. Use FortWaffles's bone adder to add bones, and use an older Modset of Brawl Box to replace the model.

Ok I've added extra bones to Ike's sword MDL0 file and tried it and it worked for a while; the final smash starts and doesn't freeze immediately and the centurions became swords.  
But after the background appears and 2-3 swords appear and attacks it freezes again along with the beep.
Would I have to rename the bones or something to fix it?

Nevermind problem solved.
I had to remove the Fit_Ike01 and metal00 with the extra bones on.

Also is it possible to change the voice clip that he says during his final smash on a 64 bit computer?  I already have wave files that would replace them but brawlbox wont let me.
