Custom Sounds

So I've been using other voice paks and they're great and all, but I was wondering if it was possible to make/import your own sound bytes into Dragon Nest for abilities and such. An example would be a sound byte of Captain Falcon saying "Falcon Punch!" instead of whatever the Mercenary says for Demolition Fist, "Falcon Kick!" for the Soccer Kick Combo, or even Ryu's "Hadouken!" for Impact Punch. Of course I would like to do more, if any are at all possible, but the aforementioned are just what came to mind first. Thanks in advance.

Should be able to just modify the pak file with the sounds in it.
